Fellows,
I am really considering rechambering a 458 Tropical to a 470NE. Does anybody out here have any expierence with this particular project. I am sure that many of you have either considered this or have actually done the deed - so to speak. I am wanting about a 10 1/2 pound rifle when it is all said and done, no scope but good express sights. Can it be done and is it worth it? I have wanted a good 470NE for some time. Last time (this last March) I was in Europe the prices for the a Holland and Holland 470 were outrageous. Well probably not outrageous for what you were getting but far above my "allowance" for guns.
Cheers
Trex

Why not the 450 3 1/4 or the 450 #2? Neither would require the barrel to be re-bored and either is a good as a 470. Much more traditional in a single shot to have a 450 3 1/4.

Mickey,
Good idea - I had given this some thought. However, at present situation (two kids and more on the way) I have been booted out of my reloading room (read here childs room now). Therefore, I have packed away my reloading gear and am awaiting the money fariey to bring me some moola to build a shop out back. Until then I need ammo that can be purchased (i.e. Federal) and shot without much ado. If I had the shop up and running then I would love to do a 450 ore even a 500. Thanks for your thoughts.
Cheers
Trex

My double rifle in 450 No2 is my favorite rifle, However You will not gain enough of a ballistic advantage to make rechambering to a 450 Nitro or a 470 worth the expense or trouble in finding ammo. I would just kep it a 458 of maybe go to a 450 Lott.
Save your money and get a double rifle
Properly loaded there are no flies on a 458, and it has the added advantage of chambering easily/readily found ammo.Save up for a double you will be glad you did.

If money is a consideration, then you want to stay away from factory ammo for the 470NE (i.e. Federal) @ $240 per 20 round box, you can load a hell of a lot of 450NE!
The Ruger No1 H tropical chambered for 458 Win Mag can be re-bored, and chambered for the 470NE, but only those rifles below a certain serial number. I don't remember what the cut off number is, but it is a way back. It seems the quarter rib screws, and positioning pins are seated to deep in the barrel steel, and the chambering will cut into the bottom of thse holes, or leave the steel too thin under them. The 450NE3 1/4", and the 450#2 NE can both be chambered in the No1H 458 win Mag without hitting them, but the best re-chamber job is to the 458 LOTT, and it can be loaded down to the 450NE 3 1/4" pressures, and velocities without any trouble at all! No extractor work at all, and factory ammo is available, as well. In a pinch, factory 458 Win Mag ammo can be safely fired in the Lott chamber! Once the brass is aquired, the LOTT is cheap to load, and the choice of cheap .458 dia bullets is inexoustable!
I have a brand new, un-fired Ruger No1 H 458 Win Mag on hand, that is scheduled to be rechambered to either 458 LOTT, 450#2 NE,or 450NE 3 1/4", as we speak! I'm leaning toward the 458 LOTT!

.458 WM, .458 Lott, .450x31/4" NE, .450 No.2, .470 NE etc, etc, are all pretty much clones. Why not step up a notch for a real improvement in horsepower with a .500x3"NE??
The astronomical cost of .470 NE ammo makes it a handloading proposition anyway!
Cost of rebarreling wouldn't be much different to re-boring and re-chambering for .470 NE, and in a properly stocked and headspaced falling block action like the Ruger No.1, at 101/2 pounds it would be a pussycat to shoot.
I used to benchrest a .500x3" NE Westley Richards Falling Block, complete with steel butt-plate, that all up weighed in at 9 pounds! A mate has a Ruger No.1 in the same calibre, and it too is gentler on the shoulder than my 11 pound .470 NE. Just something about the cartridge that makes it easy to shoot, and seems to be inherently accurate. There is a good range of lighter projectiles available for range plinking or hunting lighter game, such as Woodleigh's 440 grainers.

I agree with 470Rigby, if you don't mind rebarreling, the 500NE is one of my all time favorites. The recoil of the 500NE is not soft, but is different from any bottlenecked cartridge. The BN cartridges seem to "SNAPP" the recoil to give the FELT RECOIL a sharper jab.
Just rebarreling is not all that will be done, however, even with the 470NE. Extractor, and opening the loading trough for the large rim of either, as they are both built on the 500 case!
I have had several No1s chambered for NE rounds over the years, and I loved every one of them. I'm now thinking about going the other way, as I need one re-barreled, and chambered for 9.3X74R,for a scoped rifle to go along with my 9.3X74R double rifle.

470R,
Was this with full power loads?
How many shots to a session?

Yep! 10 shots was about the limit though! I still remember shooting it in a 20 round Single Shot Rifle event at a BGRC event in Sydney - 10 shots taken in the sitting position too! Won the event against blokes shooting .303's and the like!! - but I was a bit younger and a bit more  then!
BTW - I know the bloke that picked up those Simplex .500 NE dies - he bought them for speccing and will resell them - HIS asking price is now $180! Let me know if you are still interested....

Actually I don't mind the sitting position for big bores if you sit on the ground.
It's the sitting at the bench position which I try to avoid with my lightweight 470!

Flash!!
You cannot rechamber a 458 to a 470 N.E., you can rebarrel it, or you can do a 450-3.25 rechamber....

470R:
If that Ruger No.1 .500 Nitro belonging to your mate (PP..?)is the Vinny-engraved Pedersen-built rifle commissioned by Norm C_, everyone up here agreed that it was bloody brutal to shoot with full loads! I never fired it, but the maker, and Dave L_, both experienced big-bore users, had NO nice words to say about that rifle with full loads! Its an easy cartridge to load down, though, as you say.
Trex:
Plenty of good advice here, and the Lott makes most sense, but I would never chip a fellow shooter for preferring a classic cartridge, even at greater expense. Nevertheless, hiding a can of powder, dies, and a box of .450 Woodleighs at the mate's place, and slipping over for a 'social visit' every couple of weeks, would seem preferrable to rebarreling to .470 and then paying 12 bucks a round!

4seventy,
I was answering Trexs question, you cannot "rechamber" a 458 to a .470, that seemed to slip past some of our posters according to their answers..it requires re-barreling...
Why would you think that applies to you?

Dugaboy1,
You want to trade that "Brand New Ruger #1 In 458" for a re-chambered #1 in 458 Lott?
I've just recieved a #1 chambered for 458 Lott. It's original chambering was 458 Winnie.
I have not shot the gun as of yet. It has a very nice piece of wood on it, with a few dings form recoil I suspect. The bore is very good and has had new express sights installed. It has a Decelerator pad and mercury recoil device installed.
I would include the dies for it.
Let me know here or at my E-address.
mag4570@hotmail.com or powellrprp1@cs.com
Thanks,
Roger QSL

No, it was built by Jack Millar - maybe it is heavier and/or better stocked than the one Vic built???

Ross Seyfried wrote of just such a conversion (reboring a .458 1-H to .470NE) in Petersen's Hunting about 15-20 years ago.
Perhaps someone can reproduce the article for you.

A link on the .458 #1 caliber changes that shows some options from a very good gunsmith I have used and I could recomend. Just go for the .577

I'd like to have one of these to compliment my 470 double.

I agree that if cost is an issue, it's better to stay with the 45 caliber. Bullets are a lot cheaper.
I have this one and love it. It was a 375 that was rebarrelled to 500 Nitro Express 3 1/4" and it is just too much fun! It will cost you at least 1000 bucks to rebarrel, depending on options you want like quarter rib, sights, etc...plus brass, dies, bullets...it is a lot cheaper to simply rechamber to something like the previous posters have said.
Cast bullets are a lot cheaper to shoot no matter what you're shooting...so check them out when you decide what to do.
Let us know what you decide...

I had Kevin Wyatt rechamber a No. 1 Tropical in .458 WM to .450 NE, and it worked pretty slick, the reamer cleaning up the belted Win Mag chamber beautifully. A little tweaking with the extractor and a smidge off the top of the breech block and I was shooting. Agree the .470 would be a rebarrel.

Hello; I'm new to these forums, so please forgive me if I ask questions already answered. Can you chaps recommend someone to do re-chambering and other work (ribs, etc.) on Ruger No.1s? The link to Bowen's rifle work mentioned is broken. Any experiences, good or otherwise, would be welcome.
Thanks.
Doug.
