Rechambering a Ruger No. 1
      #92599 - 25/12/07 08:44 AM

I currently have a Ruger No. 1 Chambered in .300 Winchester Magnum that I am considering re-chambering to something a bit larger (45-90 etc.). Does anyone know of any gunsmiths who have reasonable prices for something like this? I’d probably need a new barrel to do this as well.

Thanks
Pat

I am not in the locality to recommend a gunsmith, but have you thought of .450 NE or .450#2.

I love No.1's but I went the other way from .300WM to 6mmBR Norma.

Actually those and the .500NE are very intriguing to me but I don't know much about them.
I would love any info you could pass on regarding the .450N# .450#2 .500NE .470 Capstick or any other big bore "dangerous game" cartridges.
I honestly don't have a feel for them (recoil, versatility, trajectory, etc.).

Thanks

Call PacNor (google 'em) and they can tell you what they barrel for and chamber. They make one of the most accurate barrels you can get - way above what the Ruger can take advantage of, but having a great barrel for reasonable cost is a nice thing.
; Harry McGowen is another you could call.
; That Ruger would make a nice .50 Alaskan - 520gr. at about 2,100fps. There is really no need for longer cases uneless you want to burn a lot more powder for little reward. (like 100fps) The .50 Alaskan uses easily aquired .348 brass blown out straight - "0" case loss in forming. After that, a set of dies from CH4D will do the rest. Normal powders like Hodgdon's Extreme H4895 & H4198 will give virtually the same pressure and velocities winter and summer, without presssure spikes. RCBS 550gr. mould was very accurate for me in my RBlock .50 Alaskan. Due to pressure limitations of the rolling block, I only ran 450gr. to 1,900fps. Harold Johnson, who designed the .50 alaskan on a m71 Winchester aciton, called it his bear stopper. He was from Cooper's Landing, Alaska. His modified 450gr. jacketed bullets ALWAYS exited the brown bears he shot, not matter from which direction. North or South, including quartering shots - all exited. He used a cut-off 750 gr. boattailed steel cored .5 browning bullets at 450gr. and reversed them for cup-pointed solid bullets. He also said the cavitation and internal damage was something to behold, due to the cup point. That was at a mere 1,850 to 1,900fps muzzle velocity. Good enough for me.
; You just made up my mind on what to do with my own 'spare' Ruger #1.

I suggest that you swap or trade the 300. Get a 45-70 or 458 Mag to play with. If you want more after trying full house loads with either of these you can re-chamber then.
Full house loads with a 45-70 will get your attention when compared to the 300.

Gentlemen,thank you for your swift responses. I truly enjoy learning from those more experience than myself. The .50 Alaskan was indeed a cartridge I found intriguing but was not aware that it was that potent!!

I have #1s n .375 H&H (most accurate load to date is a 300gr SGK at just over 2500fps) as well as a .45-70 (I've cranked out some hot loads 535gr at just over 1800fps, gas checked of course...man do they rock your world without much pain...until you shoot strings of them off the bench...then they get to you).

I wish .50 cal bullets were as "cheap" as the .458 diam ones but I have access to an accomplished bullet caster
any other opinions or thoughts are welcome and appreciated!!

Strangely enough my .300 win mag hurts more than my 375H&H or my .45-70!!!!
My brother also informed me he had the same experience when he shot them. We both have different body types were he is 6 feet 2 inches tall and 175-180lbs and lean and I am 5feet 9 inches at 220lbs (I’m a weightlifter-formerly natural Bodybuilder and power lifter so my weight is distributed totally different from his). Someone mentioned the “rocket effect” to us but I haven’t investigated that too much.



Thanks

I also found the .358 STA interesting as I enjoy my .375 H&H as well as my 8mm Rem Mag. I don't know much about it aside from the numbers indicate it is a STOMPER!!

Pat- I too would ranther shoot my .458 than any bloody .300 mag. It's that sharp, high velocity crack in the recoil I don't like. I did have one .330 I chambered up on a P14 action that didn't kick much at all, but I have no use for small pills on big game. For me, the 7mm mags, .300's etc have no use on big game.
; The .358 STW sounds interesting but I don't think there are any worthwhile bullets for it. I would think most normal bullets would be too soft. I'm not sure any American-type ctg. needs to burn 100gr. of powder. of course that's just a personal opinion as I have no use for sharp kickers. I shot a fellow's .338 UltraMag and that was wayyy over my recoil likes, yet the .458 doesn't bother me.
: The Ruger needs something 'secial', I agree. I'd pick a ctg. somewhat over .40 cal. personally. High velcoity little bullets don't impress me, except for the .172" and .204" variety on gophers.
: The older I get, the more I appreciate stuff like 9.3x62, 9.3 x 57 and the 9.5 versions of both of those rounds for a medium bore. The 'normal' .458 2" and .450 Marlin ctgs. & perhaps the .45/70 in the .458 cal. If Marlin made their levergun in .450 Marlin with a 22" barrel, I'd have one today for my guide and camp gun. The two rifles I've had in .458 2" both made 2,060fps with 510gr. Winchester Solids. Considering the .450/400 does 2,050fps with 400gr., I guess the little 2" .458 is OK! Elmer thought so.
; I am still thinking on a .50 Alaskan (or maybe a .50/90 Sharps for my #1. The .50/90 will do about the same, but a slighlty reduced pressure. I wonder how a hardened 700gr. .50 cal slug would penetrate if driven around 1,700fps? perhaps 1,650fps with a .5 Browning bullet with steel core? Elmer thought 700gr. paper patched slugs were great from his old re-chambered Sharps (.50 3-1/4") at 1,340fps. I think Veral Smith would make the molds. Hmmmmmmmm

SSK has on their web page the 50-3-1/4"-750, which uses .50 BMG projectiles (up to 750 grains I suppose). I know for match use there are .50 BMG projectiles which hit 900 grains. Out of a nice heavy single shot I bet that would be one heck of a round.

Good grief!!! Something of medium power (45-90, .50 Alaskan)is what I’m looking for. I was told that the 450NE 3 1/4 is a pretty manageable cartridge? Does anyone have experience with any of the .450NE cartridges?? I find myself leaning more towards lower pressure cartridges (45K or less if possible).

450#2 runs around 45,000.

I'm 5'6 and around 160. It doesent bother me at all in my double.

Bramble,
Am I correct in my thought train that the 450#2 pushes a 500 grain pill at around 2200 fps? Would that make it the equal of the .458 win mag (just at a much lower pressure)?

Thanks
Pat

375,

That's basically the jist of the 450#2. My No.1 drives a 500gr bullet at 2150 fps, and does so at a much lower chamber pressure than the .458, as Bramble pointed out. It's a very doable conversion. I had SSK re-chamber a factory .458 Win Mag, and they did a great job of it. I've since re-barrelled this gun(again in 450#2) because I just didn't care for the poor muzzle heavy balance of the factory gun.

Sell your #1 and get one in 450/400 Nitro. I used this caliber in Africa to take everything from Cape Buffalo to Wart Hog. Recoil is about 375 level, and factory ammo is available. 'Course, if you want to join the "Order Of The Sore Shoulder", get a 458 Lott. I've got one - kicks like a rabid mule, but went the long way through a Buf with a Federal solid. OW!

Yes, thats it. The 458wm was designed to duplicate the performance of the .450#2 but at much higher pressure.

But seriously, it can be a good conversion, the big rim will give better extraction bite than the WM and in the super strong No.1 action, if you want to hotrod the cartridge then I can't imagine what you could get.
Its a great cartridge for the range, "what the hell is that" factor and the simple act of sliding a pair of 4 1/2 inch cartridges into the breach makes me smile.

The Lott uses nearly 3 times the pressure to get only 100 fps above double rifle 450#2 balistics. In a no.1 you can duplicate them as there is so much spare powder space. A square shows 465 grain solid 2210 fps at only 26,000 CUP the same velocity in the Lott is 50,000psi. Or use something like trail boss or 5744 to get 45-70 type performance for NA game.

In the .450 Assegai A square are getting 2400 with a 500 grain at around 46,500 psi. The case and the 450#2 appear to have around the same capacity although I am just working on the dimensions and don't have a water capacity for the Assegai.

Good luck with whatever you decide on, love the No.1

For a Ruger #1, consider a 45-120. Brass is better quality and cheaper that the 450#2.

If you are going to barrel, go for the 50-90!

Whilst the price bit is correct, what fault do you find with Horneber cases?

and if the cases are built to the origional specs was not the 45-120 a blackpowder case ? and thus less adaptable to nitro pressures?
Max book loads run 500 grain heads at around 1600 fps, that is not even in the same ball park. Do you have some data for its use in modern firarms?

Bramble,

I agree with you on all points. The 450#2 was designed to do what it does, from the get go. As far as brass quality goes, Horneber is First Cabin.

Midway sells Norma 45-120 brass in bulk for about $1.48 each.

They will back order a box of Bertram 450#2 brass for $110.00 if you so desire.

I have a 450#2 Jeffery and have both Bertram and Horny-berner. The rim on the Bertram brass tends to be too thick on some.

The modern brass for 45-120 is plenty strong for modern firearms.

84 grains of R15 a foam wad and topped off with a 480 grain Woodleigh is all you need.

I'm afraid I wouldn't take Bertram brass for free. Of the 20 I got, less than half were functional. The rest had off center flash holes, no/incomplete flash holes, thick rims, etc.....Horneber is the way to go. It's not like a guy needs 500 rounds of the stuff. I'd venture a guess that 100 cases would last most guys a long, long, time. Besides, if I'm going through the trouble of building a British, or Continental styled gun, then it's going to be chambered in a British or Continental cartridge. Were it a '74 Sharps, hey, a 45-120 would be great. Different strokes for different folks.

For someone in the US looking for something larger than .375 for the No. 1, either .450/.400 3" NE or .450 3 1/4" NE make the most sense by far. Both can be loaded up or down in the No. 1. You could simply trade or sell your .300 and get a No. 1 in .450/.400, or wait for Ruger to chamber it in .450. I can't imagine that they won't, since Hornady is going to bring out the ammo. Hornady is making factory ammunition as well as bullets and brass in .450/.400, and is working on the .450 (including softs and steel jacketed solids in the correct 480 grain weight). I've been using their .400 brass for a while, and just bought another 100 cases. I think it's probably the best flanged nitro brass that's ever been available, and I imagine the .450 will be excellent as well, and it's cheap.

I'll have to agree about the Bertram. I would never choose a caliber that would force me to rely on Bertram brass at all. It's as bad or worse than what's been described. It isn't better than nothing. Horneber is pretty good, but isn't easy to get here - and it's expensive.

It was actually designed to duplicate the .450 3 1/4" NE.

Quote:

Not even close. CIP MAP for the .450 No. 2 is 40,610 PSI and for the Lott is 62,366 PSI. That's the legal max for both, and factory ammo is loaded to somewhat under that.

Quote:

A square shows 465 grain solid 2210 fps at only 26,000 CUP the same velocity in the Lott is 50,000psi.


.

CUP isn't PSI. CIP has the MAP for the .450 No. 2 set at 40,610, and that ain't arbitrary. It's there for a reason.

A-Square's data makes for entertaining reading after a few stiff single malts, but is an insider joke in the industry, as few have been able to come anywhere close to duplicating it. As an example, a manufacturer (who will remain nameless) brought out ammunition for some of the British Flanged Nitro Expresses (I have notes on one in particular, which I won't specify). During their testing, they tried some of A-Square's data, which showed 2150 fps in a shorter than standard barrel at way under CIP max average, in their new state-of-the-art CIP spec pressure gun. They got the same 2150 fps velocity alright, but at 10,000 PSI higher pressure than was claimed, roughly 30% higher and 11% over CIP MAP. BTW, they settled on a final load for their factory ammo that tested somewhat under CIP max, and submitted the ammo to CIP for testing. Their results checked out, and the ammo was CIP approved.

Quote:

In the .450 Assegai A square are getting 2400 with a 500 grain at around 46,500 psi.




I'll believe that when somebody that actually has a pressure gun tests it.

I wonder what the largest diameter cartridge you can fit in a No. 1 action would be. I would think somewhere around .600? Thanks for all the reading everyone always a pleasure.

Thanks for that 400.

With ref to the .458 WM comment please see the winking smilie. and refer to the post I was replying to.

I was in no way indicating that there is a direct comparison to be made between CUP and PSI, that is why I indicated the different units. Not withstanding this if one takes the MAP the 450#2 uses 73% (approx) to acchieve the same performance as the 458 Lott does with 81% of its MAP.
In my considered opinion the MAP for the 450#2 is on the low side as it was standardised (or re-standardised) quite correctly with due regard to the firarms in which it may be fired, many of which are quite old now. We were however discussing a Ruger N0.1 which my experience of, suggests is quite capable of handling far more pressure, as is, again in my opinion, the case design under discussion.
I am not advocating "hot rodding" cartridges, but a lot of people like to do so. I was rather abstractly discussing the possibilities that exist with such a massive bottlenecked heavy case.
Such discussion take place about the 45-70 every day of the week.

Well that is all very interesting. It seem that there is always somebody that has the inside track on things, but of course it is all too hush hush to publish or reveal the sources. That is a shame for us mere peons, but does I'm sure make the "insiders" sleep better in their beds at least.

Pressure testing as you know, has many variables, from primer lot, powder lot, case lot (make), case neck stiffness, ambient temp, crimp, throat length, rifling twist and exact barrel dimension, barrel surface finish, wear ect, that exact duplication of test results is difficult on a week to week basis let alone in different rigs in different places at differnt times. So much so that major ammunition manufacturers alter their loading after testing from one bulk powder to another.

But I am glad that you have raised the issue and I will write to A Square tonight as it appears that I will be in danger by relying on their loading data. I am sure that they will be disapointed that their data (which seems to be one of the very few that do publish such) has been a total waste of time, money and effort and left them open to litigation for their slipshod methods.

Quote "I'll believe that when somebody that actually has a pressure gun tests it." End quote

Well A Square did, they invented it and standardised it. But please refer to my comments below.


This is not designed as an attack on you. I read a number of posts recently where you were praised to the heavens. I am quite prepared to believe that you are as well connected as you state and have access to data that the rest of us do not. If so Sir, then please share your credentials and put that information out with its sources for all to peruse and verify.
If you know for sure, that A squares information may be wrong by as much as 30% then it would appear to be morally incombant upon you to supply people with the sources of this empirical data so that such a dangerous publication can be challenged and withdrawn from print before one of us gets hurt.
To just rubbish the work by inuendo and rumour of others without evidence, just smacks of sour grapes and proberbly borders on the libellous.
It would seem that if forums are not for the free exchange of data and information then they just descend into a pissing contest.

Gents, I have actually been interesting in purchasing A-Square's reloading manual as it seems as though it would load data and information on cartridges that would not exist in most reloading manuals. Is it worth the $36.00 (plus shipping) (American dollars) that I see it commonly being sold for? I enjoy reading about cartridges their histories, uses and comparing them. So far the only data I’ve been able to find (other than online sources) for less common cartridges like the NE cartridges has been in my “Cartridges of the World” book and it only has a few loads for some cartridges and some of those are without specific powders or load amounts. It would be very nice to have a book that delves into this area of cartridges if it is a quality book.

Thoughts?

Thanks
Pat

Quote:

I was in no way indicating that there is a direct comparison to be made between CUP and PSI, that is why I indicated the different units.




Then why did you attempt to compare them?

Further, here you make the claim that the .450 No. 2 achieves standard performance at 11000 PSI below CIP MAP:

Quote:

Not withstanding this if one takes the MAP the 450#2 uses 73% (approx) to acchieve the same performance as the 458 Lott does with 81% of its MAP.




And here, you make the patently absurd claim that the CIP MAP for the .450 No. 2 was set artificially and arbitrarily low because of old and weak rifles:

Quote:

In my considered opinion the MAP for the 450#2 is on the low side as it was standardised (or re-standardised) quite correctly with due regard to the firarms in which it may be fired, many of which are quite old now.




Which is it? Your arguments are inconsistent nonsense.

You don't know what you're talking about anyway. If the chamber pressure of the .450 No. 2 is lower than all other flanged nitros in the same performance band, and if CIP's intent was to set the MAP for the .450 No. 2 "on the low side" out of concern for older rifles, why would they set it HIGHER than the other flanged nitros in the same performance band, such as .470 Nitro Express and .500/.465 Nitro Express which are chambered in rifles that are almost always newer than those chambered for the .450 No. 2? Because your statements aren't true and that isn't what they did. The original pressure standards - bolt thrust measured using the base crusher system and stated in tons of BaseCUP- weren't industry standards in Britain, they were part of national proof law. When Britain joined CIP in 1980, CIP's entirely different standardizing methodology - chamber pressure, now measured by piezo electric transducer and stated in PSI - became the new legally mandated national proof standard, and it was necessary to restate the original pressure standards using the new and fundamentally different system. The intent was to restate the original standards, not change them. Like the rest of the British flanged nitros, the .450 No. 2 retains it's original pressure standard, restated using the current legally mandated methodology.

Quote:

We were however discussing a Ruger N0.1 which my experience of, suggests is quite capable of handling far more pressure, as is, again in my opinion, the case design under discussion.




I didn't say that it wasn't. The above statement is in no way relevant to your original statement.

"A-Square's data makes for entertaining reading after a few stiff single malts, but is an insider joke in the industry, as few have been able to come anywhere close to duplicating it. As an example, a manufacturer (who will remain nameless) brought out ammunition for some of the British Flanged Nitro Expresses (I have notes on one in particular, which I won't specify). During their testing, they tried some of A-Square's data, which showed 2150 fps in a shorter than standard barrel at way under CIP max average, in their new state-of-the-art CIP spec pressure gun. They got the same 2150 fps velocity alright, but at 10,000 PSI higher pressure than was claimed, roughly 30% higher and 11% over CIP MAP. BTW, they settled on a final load for their factory ammo that tested somewhat under CIP max, and submitted the ammo to CIP for testing. Their results checked out, and the ammo was CIP approved."

Well that is all very interesting. It seem that there is always somebody that has the inside track on things, but of course it is all too hush hush to publish or reveal the sources. That is a shame for us mere peons, but does I'm sure make the "insiders" sleep better in their beds at least.







Your sarcasm is wasted on me.

Quote:

Pressure testing as you know, has many variables, from primer lot, powder lot, case lot (make), case neck stiffness, ambient temp, crimp, throat length, rifling twist and exact barrel dimension, barrel surface finish, wear ect, that exact duplication of test results is difficult on a week to week basis let alone in different rigs in different places at differnt times. So much so that major ammunition manufacturers alter their loading after testing from one bulk powder to another.




In order to maintain level pressure and performance of each subsequent lot of ammunition, they have to adjust their powder charge when they go to a new lot of the same powder, because the density of each lot is rarely the same, and the difference, frequently significant with canister grade propellants, is by definition usually more significant with the non-canister grade propellants that the commericial loaders use. Are you just now discovering this?

Quote:

This is not designed as an attack on you.




Clearly a lie.

Quote:

I read a number of posts recently where you were praised to the heavens. I am quite prepared to believe that you are as well connected as you state and have access to data that the rest of us do not. If so Sir, then please share your credentials and put that information out with its sources for all to peruse and verify.
If you know for sure, that A squares information may be wrong by as much as 30% then it would appear to be morally incombant upon you to supply people with the sources of this empirical data so that such a dangerous publication can be challenged and withdrawn from print before one of us gets hurt.
To just rubbish the work by inuendo and rumour of others without evidence, just smacks of sour grapes and proberbly borders on the libellous.




Not even a good try. Some of the information I get from the trade is confidential, and you knew that when you posted the above.

I've had complete head separations on the second loading with their brass, bullets that weighed 15 grains less than others in the same box, dimensions that weren't within standard...If nothing else about their products is reliable, why would a reasonably prudent person assume their pressure data to be reliable? When I see pressure data that different from others in the industry, I know which one I believe. I had a copy of their manual, and destroyed it because I didn't trust their data. I avoid their products like the plague, and am not the only one. Ross Seyfreid has said so twice that I can remember in Double Gun Journal and Handloader magazine.

Quote:

It would seem that if forums are not for the free exchange of data and information then they just descend into a pissing contest.




They are for the exchange of information, which also includes experiences and opinions. Some, like you, aren't interested in any of that, and prefer creating pissing contests because you find them more entertaining.

I didn’t compare them, I just made a statement.
You compared them or assumed I had.
Being so much better informed than me, you assumed that I didn’t know the difference and was making a direct comparison. I wasn’t, I just didn’t have the data to hand in the same units.

I don’t make any claim. I am simply reporting A squares data.

“Any shot you want” 1996 Pg. 550.

2158 fps @ 26,000 CUP

ibid. pg. 548 Pressure allowable MAP 35,559 CUP

= 73.11%

False claim.? I expressed it as an opinion. Many older cartridges have their MAP or MIP set low because of the age of the firearms that they may be discharged in. The 45-70 is a notable one.
I would be amazed if in setting a MAP and MIP for the 450#2 due consideration was not given to such matters.

Inconsistent nonsense.

In changing from base thrust to an entirely different measurement of chamber pressure, I can only assume, not being an insider, that a cartridge of known base thrust was fired in a chamber that allow the recording of piezo psi. I may be wrong but it seems the only logical method of transferring from one standard to another. That chamber pressure happens to be higher than the .470 NE. Where did I ever say that it was not so?

Quote “The intent was to restate the original standards, not change them” End quote
They didn’t restate the original standards. A new method was used, one cannot simply restate empirical data if one uses a different method.. They were standardised or re-standardised by a new method.

Quote “You don't know what you're talking about anyway. If the chamber pressure of the .450 No. 2 is lower than all other flanged nitros in the same performance band “ End quote.

I have not stated that, throughout the entire thread, I have never stated that or used any combination of words that suggest that.
In fact if you refer to my post #92663 several lines above you will see that in answer to the original poster I gave the approx. MIP as 45.000psi
Ibid. pg. 548

No my sarcasm was clearly not wasted it was well aimed and seems to have hit the mark as the tone of your response indicates for all to read.

Quote ”Are you just now discovering this?” End quote

Why would I be the one just discovering this ? Is it another trade secret that only a few are allowed to know? Oh dear is it like the magicians guild have I just broken the golden rule?

I am however, glad that you acknowledge it. I must also take it then, having picked at almost everything else I wrote, that you are not at issue with the essence of that paragraph about the near impossibility of duplicating another’s pressure test data given different parameters. Thus rubbishing A squares data based on anthers test results under different circumstances was an unwarranted, unsubstantiated act.

Quote “Not even a good try. Some of the information I get from the trade is confidential, and you knew that when you posted the above.” End quote

How on earth would I know that. I do not know you. You do not say who you are and just keep referring to your highly confidential sources. This appears to be manifesting as some form of megalomania.

Quote “I had a copy of their manual, and destroyed it because I didn't trust their data.” End quote

Destroyed it? What couldn’t trust yourself not to read it again? Afraid that aliens would get hold of it and contaminate all of the rest of your loading data.? What did you do, take it in the yard, burn it and stamp on the ashes?
Bit of an extreme reaction wasn’t it?


I must return then to your unsubstantiated attack on A Square.

Are we now given to understand that your distrust of A Squares loading data and your reference to them as an “insider joke” is based on nothing more than your admittedly unpleasant, experience of bad cases and incorrectly weighted heads and that Ross Seyfreid has said it twice.
Did you discuss these problems with A square ? and if so what was their response?

Pissing contests.
If you go back and read your post 93020 You will see that you jumped down my throat and got all smartarsed over what was humour. You see the smiley and the next line that starts “ But seriously”. “But seriously” may be taken commonly to mean that what was said before was not serious.
Not a polite “ I disagree with your data and can you explain your position” but a tirade about how useless A square are.
What you did not comment on and should of, was that I mistyped 3 instead of 2 when discussing the Lott.
Ibid. pg. 554 2251 fps @ 58,500 psi

Quote ”Clearly a lie.” End quote

It is also manifesting as paranoia. If you read the rest of the paragraph I stated that I was prepared to believe you if you could substantiate what you said. Clearly you cannot. As my pals in Missouri would say “Show me”
If you think that resorting to sarcasm is an attack, then I suggest that you re-read your post. I can think of no better response when somebody bases their position upon “secret” information. That is a crock and you deserved to be called on it.
It wouldn’t work in medicine or engineering, imagine posting that “Fred Bloggs and co. is rubbish, the bridge they built will fall down. I can’t tell you how I know but don’t ever drive over it” or “ Don’t have the Flu vaccine this year, I have good inside information that its going to make you sick, they got the mixture wrong. I cant reveal my sources you just have to trust me on this.”
Would you expect any reasonable person to take this seriously?

To close.
I have no connection what so ever with A Square aside from owning one of their books.
It however, ill behoves anybody I believe to purport to be an expert and to attempt to ruin somebody’s business without good evidence.

It wasn't an opinion, which would indicate some level of knowledge on your part. It was baseless speculation on your part, which was wrong. If you knew much about double rifles, you'd know why they didn't want to do that with a double rifle cartridge.

Wrong again. I didn't say it wasn't labor intensive. There is no conversion formula, so it took a lot of testing to arrive at the equivalent of the original standards in chamber pressure, and they didn't get it right the first time.

Quote:

Quote ”Are you just now discovering this?” End quote

Why would I be the one just discovering this ?




Because you missed it entirely. You mentioned a number of other factors which are fairly constant for a given manufacturer as the reason for the need to adjust their loads periodically, which isn't true. It's primarily due to the differences in lots of the same bulk powders.

I am entirely at issue with it. A difference of 10,000+ PSI with the same kind of powder pushing the same weight bullet to the same velocity isn't due to the reasons you gave, and to suggest that it could be is absurd.

You wrote "this is not designed as an attack on you" after having written a long post, which one hopes you re-read before going forward, that was unmistakably precisely that. Since you were able to do so, you either suffer from cognitive dissonance (you're irrational), or you're a liar, possibly both. Which should I assume? I won't waste further time with either, so I won't bother with the rest of your points.

Quote “Right, you give advice without even bothering to check your sources. CIP MAP for the .450 No. 2 has never been 45,000PSI.” End quote

The thread went.

“Good grief!!! Something of medium power (45-90, .50 Alaskan)is what I’m looking for. I was told that the 450NE 3 1/4 is a pretty manageable cartridge? Does anyone have experience with any of the .450NE cartridges?? I find myself leaning more towards lower pressure cartridges (45K or less if possible).

Thanks
pat “

My reply

“450#2 runs around 45,000.”

So my reply was exactly inline with the question. The MIP of the .450#2 is around 45k so its MAP is less. Just what the poster of the question wanted.

Ibid. Pg. 548 Max Indicated 45,907 psi

I didn’t even suggest that you could or should load the cartridge hotter.

“in the super strong No.1 action, if you want to hotrod the cartridge then I can't imagine what you could get.”

“If you want to” means exactly that, i.e. I’m not going to.
“ I cannot imagine” means exactly that. I.e. I am not venturing an opinion.



Quote “It wasn't an opinion, which would indicate some level of knowledge on your part. It was baseless speculation on your part, which was wrong. If you knew much about double rifles, you'd know why they didn't want to do that with a double rifle cartridge.” End quote

Didn’t want to do what? Give consideration to the age of the potential recipients of the cartridge.? This reply makes no sense. It cannot be baseless as the MAP of the 45-70 was kept low because of the Springfield 28,000 cup.
“ The performance of the .45-70 Government is impeded only by the strength of the rifles for which it has been chambered” “Handloading is particularly advantageous when shooter possess a Ruger No.1”

Lyman 48thEdition Reloading manual Pg. 299


Quote “Wrong again. I didn't say it wasn't labour intensive. There is no conversion formula, so it took a lot of testing to arrive at the equivalent of the original standards in chamber pressure, and they didn't get it right the first time.” End quote

Who mentioned labour intensive ? You said that they weren’t re-standardised just “restated” Clearly now you have changed your mind and they indeed were re-standardised by the new method and more than once according to you.

Quote “Because you missed it entirely. You mentioned a number of other factors which are fairly constant for a given manufacturer as the reason for the need to adjust their loads periodically, which isn't true. It's primarily due to the differences in lots of the same bulk powders.” End quote

If you read the paragraph I was discussing the near impossibility of repeating pressure test results. You had used this failure to attack A square. I am glad that you now agree that you attack was unwarranted.

Quote “I am entirely at issue with it. A difference of 10,000+ PSI with the same kind of powder pushing the same weight bullet to the same velocity isn't due to the reasons you gave, and to suggest that it could be is absurd.” End quote

Ibid. pg. 151 Primer change V pressure and velocity
“ The results are quite interesting. The total spread in pressure, from the cci 200 to the Winchester Large Rifle Magnum was 12,800 psi. This is a very significant change”

Ibid. pg. 146
“assume a change up or down of 0.9 fps and 66 psi with each degree F”

Ibid. pg.153 Case change v pressure
“”a spread of pressure of 4300 psi”

Ibid. Pg. 156 Primer lot change
“But there is still a total spread of 4,700 psi

Ibid. 157 Case lot.
“” Though the spread on this experiment was only 5,000 psi, this cannot be treated as conclusive or applicable across the board”


So the mere change in primer can result in a 12,800 psi spread. So why am I being absurd to suggest that, your Insider secret testing using components that could have been entirely different to those used by A square in obtaining these figures is not a good empirical reason to refer to somebody’s company as an “ Insider joke”.
You refuse to divulge any details of this supposed test or the parameters under which it was conducted and you have the effrontery to accuse me of absurdity.


Quote “Because I made it crystal clear by making a point of not divulging it.” End quote

So because you are not prepared to support your position with any published data whatsoever, do you fondly imagine that the claim of “confidential information” is enough to let you off the hook.? You are inferring that you are an “Insider” in the gun trade but you apparently did not contact A square about your case failures but decided instead to rubbish their company in this forum instead

Quote “(you're irrational), or you're a liar, possibly both. Which should I assume? I won't waste further time with either, so I won't bother with the rest of your points.”

You believe that I am irrational.? You Sir are the one descending into the realms of “ I know but I wont tell you how I know” fantasy
Go back and re-read your posts. You have not offered a single citation to support your position in spite of my repeated requests that you do so. You didn’t when given the opportunity to do so even support your own claim of A square being an insider joke based on the secret pressure testing but then went on about bad cases and Ross Seyfreid. You don’t even give the citation for his article for the rest of us to read it.

I didn’t attack you, I asked you to supply evidence to support your case. That is common practice in all forms of scientific study and academia.
If you have been able to go through life without anybody ever asking you to prove what you say, then you have been very sheltered.
I stated that I was quite prepared to believe you if you could supply evidence, you clearly cannot.

Quote “I won't waste further time with either, so I won't bother with the rest of your points. “ End quote.

You don’t have the time to deal with this but you have the time to be snotty to somebody who is just asking for some .470 practice loads? Post 92776

So having failed to support your position you would like the whole matter to go away so you can make unfounded attacks upon whom next?

I currently have a Ruger No. 1 Chambered in .300 Winchester Magnum that I am considering re-chambering to something a bit larger (45-90 etc.). Does anyone know of any gunsmiths who have reasonable prices for something like this? I’d probably need a new barrel to do this as well.

Thanks

: Greg Tannel, or Jerry (I think that's his first name) Weaver will do a GREAT job on your rifle.
; These guys are great gunsmiths who do wonderful work. You may get the job done more cheaply, but certianly not at the same quality. I've friends in the Western States who get no one else to do their barreling and chambering - time after time after time.
; The .50 Alaskan is a cool round for a #1. Brass is easy to make as .348's are merely blown out after necking up to .375. I use 450gr. or 500gr. .510's with the nose turned to .375 then inserted into the necked up .348 case. These are fired with a moderate load and the brass is then squared and trimmed to length. You could also neck up to .45 and use the same .50 cal. bullet base roughly turned to .458- or in two steps, oyu could neck them all the way to .50 and use 450gr. or 500gr. bullets for the forming - it's all elementary and easily done.
; The .50 Alaskan uses the same extractor as .45/70. Rim size is the same.

Thank you for your post! I assume you were speaking of the gentleman who runs this website? http://www.weaverrifles.com/index.html

Do you have any experience with the .50 Alaskan? What kind of power can you get out of one? It seems to be a pretty intense cartridge. Any idea what the pressures are for it?

Thanks

I think that you should contact Regan on the below. This is a direct link to one of his .50 Alaskan #1's

http://www.leveractions.com/RugerNo_1.htm

It is not his first one and he is a good bloke, I hunted with him in Africa last year.

I did not give you his name before as he specialises in this cartridge and the early post spoke of others

; .375 Ruger
; Ha!- I wasn't aware tht Weaver ran this site - hadn't even observed his add. I only know Weaver from his reputation at saubier.com., a sub-bore site (under .224).
; My experience with the .50 Alaskan deals with a modern made Pedersoli Rolling Block and a Shilo Sharps both barrelled with McGowen chambered blanks, #5 taper at 28" - 11 1/2 pound - both rifles. In the RB, I worked up to 2,000fps quite easily with H4198 and 450gr. cast bullets. My most accurate ammo was in the 1,800fps range with 550gr. RCBS cast FN's. Pressure would have been well below 40,000psi for the 450gr. and 550's. - just an educated guess. In a stronger or more modern action, one loads to the power and pressure levels one desires. I suspect the #1 Ruger will handle around 55,000psi to 60,000psi in this straight case. The new .348 brass is immensly strong - much stronger than most modern cases that are loaded to that prssure level. At that pressure, which would be moderate to moderately high for the Ruger, I'd think the 550gr. RCBS cast bullet should easily run in the 2,200fps range. It should then easily do 2,200fps with 520gr. jacketed ones. This is only a 2.1" case when blown out but still has slightly greater capacity than the 2.5" .458 Win. Mag. manages. Properly throated, it will generate the same velocities as in the .458 Win Mag, with the same weight bullets, but at lower pressures. This means it will generate higher velocities with the same bullet weights, at the same pressure level. I'm assuming the .458 WM is loaded to something around 55,000psi. This is fully 8,000psi (or more) approximately, lower than some rounds that are chambered in the #1 and that the #1 handles easily - more easily than most bolt guns.
; As handloaders, pressure is only as high as what we load the ammo to. We are in control unless we shoot someone else's ammo, be it handloads or factory stuff. That we or some of us are in control is perhaps a good, or bad thing, as the case may be - HA!
; The .50 Alaskan is a cool round. It demands respect. My rolling block, with it's heavy and slow hammer fall was good for 5 shot groups of 1-1/2" at 200 meters using tang peep and blade front sights and the 550gr. cast bullets - using black powder loads or smokeless - that barrel didn't care. At 1,800fps, it was 300fps faster than what a black powder load in the 3-1/4" case can deliver - and only about 5,000 psi higher pressure.

Harold Johnson, who designed the .50 alaskan on a m71 Winchester aciton, called it his bear stopper. He was from Cooper's Landing, Alaska. His modified 450gr. jacketed bullets ALWAYS exited the brown bears he shot, not matter from which direction. North or South, including quartering shots - all exited. He used a cut-off 750 gr. boattailed steel cored .5 browning bullets at 450gr. and reversed them for cup-pointed solid bullets. He also said the cavitation and internal damage was something to behold, due to the cup point. That was at a mere 1,850 to 1,900fps muzzle velocity. Good enough for me.
; You just made up my mind on what to do with my own 'spare' Ruger #1.




Daryl, a small point, but the rifle Johnson used was a 1886 Winchester originally chambered for .50-110 and rebarreled using a .50 BMG barrel. He still had it when I interviewed him about a year before his death when he gave me some of the details about this and his other guns. Fascinating fellow. He died in 1998.

Daryl,
Thanks for the response! It appears the .50 Alaskan is more flexible than I thought! I do enjoy a flexible cartridge!!

Side note:
Are the NE cartridges like the .450 #2 NE and .500 NE pretty flexible or do they have to be run at a pretty hot level to get safe and accurate results?

Thanks
Pat

9.3 - you're right, his was an 86. Through the 50's the 71 seemed to become more popular for all the other wildcats on the .348 case.
; Another point, Harold made his 450gr. cup-pointed 'solids' from steel core .50 browning bullets, cutting them off above the cannelure, then loading them reversed, cupped-base forward. This gave a slight ogive with a cup point. He noted they provided for exteme cavitation in the bears he shot even though they were solids and that he failed to recover any bullets from bears as all exited. His speeds were in the 1,700fps to 1,900fps range.
; Published data for the .50 Alaskan for use in the M71's or stronger actions that runs cast 485gr. bullets to 2,009fps + the 600gr. A-Square solids to 1,739fps. I'll bet that kicks in a m71. These are lever gun ballistics. They are held to 44,000PSI or less. The 485gr. load actually is in the 40,000PSI range.
; Best powders for top velocities will be H or IMR4198 and Reloader #7. I prefer H4198 as it is an extreme powder, not effected by cold or heat. Reloader #7 has shown to be very accurate for me in both .45 and .50 calibres.
; The big British cases usually have to be driven at factory levels to get proper regulation of the sights. That means full power, all the time.
; If flexibility is to shoot a wide variety of loads accurately for a wide variety of game, then the double rifles fail in that definition. They are normally a one load gun but I understand that lighter bullets can sometimes be found to shoot.
; BTW .375 Ruger - Harold made up the .50 to get more power than his .450 provided. At that time, the .450 Alaskan was running 400 through 500gr. bullets up to around 2,000fps. Due to the way FPE formulas work, bore size means nothing to the product of foot pounds energy. Harold, as many other real big game hunters knew, bore size makes a big and noticable difference on dangerous game. That is why a .50 developing 4,000fpe is more effective than a .338 producing 4,000fpe.

Re: Rechambering a Ruger No. 1 [Re: DarylS]
      #93904 - 09/01/08 01:20 PM

Does a No. 1 have any length restrictions as far as COL? I emailed several companies/as well as gunsmiths to ask them about pricing and was told by one company that the No. 1 would require action modifications to chamber cartridges such as the 450 #1, the 500 3inch etc. This is perplexing to me as I thought that one of the strengths of a No. 1 as far as modifications went was their ability to accept any length cartridge (barring of course the throat length).

Thoughts?
Thanks
Pat

I believe its as simple as milling a radius into the breechblock for the rim to clear, pretty straight forward stuff.

: Upon thinking about the rim size, it is possible the Ruger may need some milling of the trough, however, it works fine with the .608" rim of the .45/70. Due to the taper of the .500 case allowing some angle to loading a round past the trough, it's rim might clear OK with no modification. The only way to find out is to chamber the round and test for fit.
; Pat, there is no limit to OAL, however the longer the round, the straighter it must be in line to the axis of the bore when chambering it and the lower the rear trough must be to clear.
: Donnley's book says the .500 3" and 3.25" (alone with the .500/.450) rim is .660" in diameter. This is only .058 larger than the .45/70's rim. That is only .026" per side, which means a .45/70 Ruger, if different from the rest, may have to be milled just a tich. I had to mill one Shilo Sharps factory action to clear the .50 3-1/4" rim of .656" while the other one we re-barreled was fine without milling.
; .026" is about 4 thicknesses of 24 pound in-jet printing paper. Only the centre radius must be that deep as the rim is round. It could be done with an emery stick in a hand drill using 320 grit emery and finished with 400grit before blueing.(action apart, of course)

Daryl and Steve,
Your thoughts on my question certainly make sense to me. I was a bit lost but now that I took some measurements in tune with your thoughts it makes much more sense to me now. Do you suppose milling some of block off would weaken the action much?

Thanks for your thoughts and help
Pat

milling the block should cause no problems and will not weaken the action.

I have a #1 that was rechambered to 460 G&A #2 a 500 flanged nitro necked down to 45.
All it took was the rechambering and milling a bit off the top of the breach block and the
feed ramp so the rim would clear. The rifle works great and if I could find my old notes could
figure out what the velocity was for the 500 grain .458 bullet. Final velocity was between the
.458 Win Mag and .460 Weatherby Mag. It is a fun gun to shoot recoil is substantial but only
bad off the bench.
Cheers,
fallingblock

Howdy fellers. I just found this forum. I currently own a .416 Rigby #1 and a 45-70 #1. Love them both but have been thinking for some time about converting a #1 to .450-3.25. I know that there are several places that do it. I have hear the rumors that Ruger is going to bring out a .450NE as a production rifle now. Does anyone know if this is true yet? reflex264

My reply to the post is not about re-chambering a Number 1, but rather about re-barrelling a Number 1. What I was thinking about was putting extra barrels on one of my #1's, in 256 Mannlicher (aka 6.5 x 53R) & .303 Flanged 2 1/4" NE (aka 303 British). Looking at the thread sizes tells me it is possible even if I will have to use an epoxied-in-place artillery style breach section over the threads to "beef" them up to mate with the #1 action threads. The nice thing is that the barrels are new & already chambered. Have any of you gentlemen had any experience with this? I know, I am sort of re-creating an old Fahrquarson style rifle, but it is substantially cheaper to do it this way as the last .303 Fahrquarson actioned rifle I saw was advertised at $6,000. As well, it is getting harder & harder to get barrels here in Canada, coupled with the fact that very few gunsmiths, of the few there are remaining here, carry those reamers, so if I purchased barrels, plus reamers, plus had the barrels contoured, plus had them polished & blued, it would be a substantially more expensive & time-consuming proposition, than what I am contemplating.

I apologize if this thread of re-chambering #1 Rugers was meant to encompass & discuss big-bore rifles solely.

Thank you for the bandwidth.

Old rifle nut - you can still get most excellent barrels from PacNor, already contoured for right around $200 for chromemoly and $220 for stainless. I get my chambering reamers from Pacific Tool and Gauge - $87.0 for solid pilot and $150 or so for removable pilots.
; I've used the 'collar-method' of putting barrels in an action and it works well. Due to the small calibres I used, a throgh-hole of 3/4x16 worked well, but I can see doing this with a thin-shell threade stub in the action and replaceable barrels as you suggest. It would be fairly simple job for anyone with a lathe and who makes good threads. I have several switch-barrel guns - fun- fun.

If I am interpriting what you say correctly, then I think that it could work. I am always a bit wary of epoxies due to temp and solvents (I am also a dinosaur !!) I think I would solder those bushes on personally. What are the thread core, OA and pitch of the threads on the barrels. I have the data for the Ruger ? Are the rim dia's of the two cartridges similar to avoid changing the extractor? Because the Ruger extractor is designed to move to the left for rimless cartridges then you will have some latitude here.
You have got me intrigued, I wonder if it is possible to make a stub bush for the #1 and fit a quick change pinned system for the change barrels. Intrigueing !

Regards

Not sure what you mean about epoxying - what? Soldering rasies more temp than any epoxy. If you mean locking the bushing in the #1 Action with epoxy - yes, that's what I would do, so it didn't want to loosen with the barrel.
; There are no pins needed. I would not trust pins to be secure enough - ie: tightly fit enough to shoot well.
; Barrels used for BR shooting have only perhaps 20 to 30 pounds torque. They are easily changed with a barrel clamp on the bench, and smacking an action wrench (or padded crescent) with the flat of the hand - all my barrels come off that way - easily, but never loosen one bit during shooting. - Right hand twists tend to tighten barrels.
; The barrel threads and therefore the inner thread of the bushing should be as large as possible, ie: close to the original thread size, but necessarily smaller to allow sufficient thickness of the #1's bushing.
; I thought all this was what you were talking about earlier.

Daryl.

I think that you may be looking at "Old gun nuts" post and mine together.

It was I who mentioned my irrational distrust of epoxy. From what I understood of his post I believe that he was going to fix a bush with the internal thread to suit whatever existing barrels he has and then cut an external thread to match the #1 barrel shank thread. I was commenting that I would solder such a bush on and not trust to epoxy, as I dont like them in combination with increased chamber temps in use. I always fear, although I am proberbly wrong, that they will degrade with temp soak and cleaning solvents. It was the temp rise in service on which I was commenting, not the temp necessary to solder the bush on initially.
That is why I added that I am a dinosaur. :-)

You are quite right of course about the torque necessary to seat a barrel. My takedown which is elsewhere here, unscrews with a firm slap on the forend. The machineing of course has to be spot on, which is why, I presume, that so many factory barrels are heavily torqued into position.

I mentioned swap barrels held with a pin, because the greatest variation in the #1 appears to relate to the forend and hanger tension. ( I have a long range rig #1 in 6mm BR )if a bush were long enough then it would not be necessary to disturb this in changing barrels. Just slip them in and slip them out. That comment was just my idle museing however and I cant't say that I had thought it through to any degree.

Regards
