Cogswell & Harrison .242 Vickers

I have a relatively rare "small bore" inbound - .242 Vickers Mauser by Cogswell and Harrison.

The rifle is missing its bolt so its first stop will be Steve Bertram (www.bertramandco.com) for a new bolt assembly and possibly cleanup of the metal work with a fresh rust bluing job.
While there I will have Steve do a chamber cast to confirm dimensions and exact groove diameter so I can get the correct reducing die from Corbin to squeeze a 100 grain .25 caliber down. Failing that a .243 could be "bumped up".......
Standard .242 Vickers bullet diameter was .249" but the neck and throat will tell the tale of exact bullet diameter needed.

Reloading dies were actually the easiest part, sourced a set of North Devon Firearms Service dies from "Jack First". It is said that common readily available .25-06 brass can be sized in one pass then trimmed before fire forming.

I have contacted Cogswell and Harrison for whatever info they have on this rifle, will be interested to see that turns up.

Additional details when this one arrives.

- Mike

Shame its missing its bolt 3DM!
Looks a pretty niffy piece of kit there, I've never heard of this calibre before.
When you do get a chance can you please put in the loading data for this as it appears to be a 'rare' bird indeed!

Re: Cogswell & Harrison .242 Vickers

A very rare chambering indeed.......apparently not too popular and faded into obscurity fairly early on.
Possibly due to the onset of WWII then after the war the hunting bans in India?

The only load data I have found is from "Cartridges of the World" as well as an article in the 1972 6th edition "Handloaders Digest" by Ken Waters.
Per Cartridges of the World the original .242 Vickers loading is said to have been 40.5 grains of "Nitro Cellulose" for 2800'/sec with a 100 grain bullet.

Cartridges of the World:
39 grains of 4350
34 Grains of 4895
both for about 2800'/sec

Ken Waters data:
42 grains of (IMR?) 4350
48 grains of H4831
no velocities mentioned; Waters' loads in his "Pet Loads" tended to be pretty hot.

The .242 Vickers cartridge is similar to and only slightly larger than the 6mm/.244 Remington so starting loads for the 6mm/244 Rem look like a decent guideline.

Right now Cogswell & Harrison are stumped because of the 4 digit serial number, they are still checking.........maybe a Vickers made and numbered rifle marked and retailed by Cogswell and Harrison? The barrel is marked "Cogswell & Harrison, Ltd" which indicates that the rifle is from some time after the 1932 liquidation and reorganization of Cogswell and Harrison.

hope its a standard length action so find another bolt will be easy
headspace is another question

Re: Cogswell & Harrison .242 Vickers

Seller said a standard M98 bolt entered and closed fine.......? Just no attempt to go farther as to install to be shootable.

Headspace should not be insurmountable because if nothing else, due to no available loaded ammunition, this is a totally handload only proposition. If close enough then fireform brass to fit the chamber and headspace.

Here's the proof marks and serial number on the action ring; will have a look under the wood when I take delivery to see if there are any other markings such as Vickers-Armstrong, etc.

Re: Cogswell & Harrison .242 Vickers

A resized .30-06 using the NDFS .242 Vickers sizing die. Several gentle passes into the FL die using Imperial Sizing Die Wax, trim to 2.38"/60mm and eureka, a perfectly formed case.
I think to avoid possible thick necks and need for neck reaming I will use .25-06 for actual shooting brass.

That is a SHORT case neck!

Re: Cogswell & Harrison .242 Vickers

This is a surprising discovery; this rifle's groove-groove measures 4 grooves and .255", a sample original Kynoch bullet is .247" diameter while the commonly stated bullet diameter was supposed to be .249".
Makes me wonder if the .242 Vickers became unpopular because of bullets essentially rattling down the bore and thus not being too accurate?

The up side of this is that a common .257" bullet is easily sized down .002" in a Corbin reduction die. Case necks may need inside reaming or neck turning........we shall see.

Something to be very mindful of when fooling with a long obsolete 95 year old cartridge that is going to amount to a modified, slightly undersize bullet, .25-06........

After forming and trimming of .30-06 & .25-06 cases with the .242 Vickers die and measuring I cannot help wondering if Manton and Kynoch did pretty much exactly that; necked down a .30-06 (.30 USG) case to nominally .242 specs? The case taper is a hair more and consequent shoulder diameter is a bit less, but base to shoulder is, as closely as I can measure, the same and shoulder angle is for all purposes the same as far as I can discern.
Yes, while the -06 case is very overbore for a ~.250" 100 grain bullet with the powders available in 1924; like all the cartridges meant for tropical use in "the Colonies" this large case at 2800'/sec meant comparatively lower pressures which were a desirable thing back then.

The adventure continues!

I wonder if the .242 and .255 calibre differences is like the .303 and .312 bore differences in naming? And .318 and .330? Using lands width rather than bore calibre.

Or something like that.

Now THAT got a chuckle out of me!......no, no way, no drill & tap, no heavy repolish and hot blue, no Weatherby stock finish.......this one gets a "gentle" restoration to what it was.
Will get a new bolt with period straight (no scope) bolt handle treatment and pear shaped Mauser knob, clean up minor corrosion on a couple of spots on the barrel and mag floor plate, re rust blue. Not re-finish the stock, just needs a refresh on a couple of dry or moisture impacted spots.

Re: Cogswell & Harrison .242 Vickers

Lancaster and Nitro John
The rifle does not yet have a bolt, we just yesterday actually got delivery. Steve Bertram is chasing one down to use in the "restoration" to shooting condition.

The ".242" undoubtedly was the expected bore at top of rifling lands while the groove depth was supposedly ~.249". Who knows now, maybe Vickers quality control for bore dimensions was not that good?
As I have sourced an original unfired box of 10 Kynoch .242 Vickers I can say with fair certainty that all the Kynoch .242 Vickers ammo had bullets of .247" diameter.

Poor consistency on bore diameters, maybe? .247" is not bad for a .249" groove diameter & likely shoot just fine.
My old 9.3x57 had .370" groove dia. and still shoots all bullets from 225gr. to 300gr. & from .365" to .367" bullets into 1 1/8" or better at 100meters - most weights are under an inch.

Yep, undersized bullets can do just fine. My R.B. Rodda .404 Jeffery (circa 1929, probably by Schüler) has groove to groove diameter of .4285" and shoots just fine with standard .423" Woodleigh's..........

18/08/19 07:49 AM
Re: Cogswell & Harrison .242 Vickers

There is a really good chance - heightened by a large capacity case to bore ratio, of increased throat & groove wear due gas blow-by from oversized cases.
While not much of a problem in low pressure or smaller cased rounds, it is still there to some extent - has to be.
My 1929 Swede though, is still shooting like a brand new rifle. Go figure.
The rifle's chamber will not allow larger than .367" bullets to be used in it's .370" bore. To use larger bullets, I would have to relieve the chamber neck with a "Chucking Reamer". Those are available from reamer makers in .001" diameter increments.

read a report about carbine 88 making by C.G.Haenel in Suhl in the 1880s. the official was complaining about the fact that production could be go much quicker if the worker's not allways bringing bear into the factory and this was not meaning single bottles.

An alternative view might be that if it allows some old rifles to actually be used, in the field, for hunting, to be fitted with a scope, then that is to the good. All these lovely old rifles filling gun safes, sometimes hundreds for a collector to me is a great shame as well.

Some hunters still can and do use open sights. Many today don't or can't. I dread the day, when I can no longer use open sights. So of my rifles, are ONLY open sights. And would need new examples to be acquired to allow modern optics of some sort to be substituted.

Some old vintage rifles, especially rook rifles and those of smaller calibre, such as .22's of sorts, do really benefit from having modern precise aiming sights available. In my youth I could crawl a hundred metres to shoot a rabbit in the head at 7 metres. Not so today.

Cogswell & Harrison....no luck.
Have heard back from Cogswell & Harrison and they have no records for rifles made by other makers and then marked/retailed by Cogswell & Harrison.
They say that all their rifles were 5 digit serial numbers while this one is 4 digit.

By the "Cogswell & Harrison, Ltd." barrel stamp it would indicate procured and stamped by them on or after 1932.

Unknown so far if this would be a Vickers-Armstrongs made rifle or if it came from the trade; have found no other markings, save proof marks, on the rifle.

Re: Cogswell & Harrison .242 Vickers

Mike, I have a pair of Vickers .318 express rifles that are dead ringers for yours. #3509 and 4069. The bolt handles are nicely turned down military handles. I bought the first one from Thad Scott back in the early eighties and it shoots well and I took it to Tanzania for plains game. The other I bought from Cabelas and unfortunately, in its past, it had been rebored to 35 Whelen, most likely due to lack of .330 dia bullets. In an attempt to bring it back to its British roots, I rechambered it to 350 Rigby mag and it shoots well with 225 gr. Noslers. Congratulations on your rare bird! If I had seen it, I would have bought it in a heartbeat! Your rifle is in good hands with Steve, if you need pics of the bolt handles for accurate reproduction, drop me a PM. Lee.

I saw on a recent thread the milling of unobstrusive grooves in the rear sight allowing a dot sight to be installed there. Now while the dot might be a star and not a nice round dot, regulative might not be affected too much. Allowing such rifles as my .450 No.2 NE to still be used. I still can use it, but have been told of severe future eye problems in a decade or two. Not looking forward to it. And will shooting of heavy recoiling firearms be possible after surgery one day?

It was made by the SA Brewing Company I believe. Now called Lion Nathan after a kiwi takeover, before they in turn were taken over by the Japs, Kirrin.

Duff Beer as made by SA Brewing, was not named after the Simpsons cartoon beer if I remember rightly. However the yanks threatened legal action for trademark infringement of a trademark class, ie beer, where they had never made any beer, never sold any beer, and never traded in beer in this trademark jurisdiction. A cartoon beer is not a real beer. However in TM matters money on legal bills matters and they withdrew their Duff Beer.

Does the Duff Beer have any Simpson's references on the packaging?

I like James Boag Premium as well.

I also will buy Coopers Sparkling Ale or Pale Ale.

I wouldn't ever bother with a XXXX or Vic Vomit Bitter.

I also wouldn't bother with a Hahn, since they were no longer a boutique winery back in the 80's or 90's. Made by an American Brewer in Sydney, called Dr Chuck (Hahn) back then. Now it is mass produced swill.

I am being unpatriotic nowadays and enjoy a Danish Carlsberg.

August 2020 update:
Late due the Wuhan virus follies.......etc.
Have sourced bullet drawing dies from Corbin and Lee to squeeze standard .25 caliber .257” bullets to fit.
Chose the Nosler 100 grain Accubond and Speer 100 spitzer flat base soft point for trials.

The rifle had to go back to Steve Bertram to have the throat deepened as current bullets sized down would not seat out to proper cartridge overall length. The rifle now has a nice target rifle grade throat and case necks only need a light reaming.
As there is no current or vintage ammo and no original Kynoch .242 bullets available I don’t consider this throat alteration to be of huge consequence to the original rifle and does allow it to be shot with modern components.

Weather permitting this week I’m going to work up a load with IMR 4350 and the 100 grain bullets to get close to the vintage advertised velocity of 2800’/sec.
This rifle has a 24” barrel and the original Kynoch advertised velocity was likely obtained with a 26” or 28” barrel so 2750’/sec might be a sweet spot.

Re: Cogswell & Harrison .242 Vickers

Fingers crossed for you 3DM, it will be rather interesting to see how this this old girl really goes.
I totally agree with what you had to do to make it work, virtually giving it a bit more 'freebore' so to speak, the chamber is still original so it is a win-win for you mate.
It would seem that with a larger case capacity than the .244 Rem, you should get easy 2800fps with the 100gn pills, but the proof will be in the pudding when comparing a 'preferred velocity to your sights.
Don't be surprised if you get a few 'sweet' spots along the way.

50 Yards.....
The 1 5/8' group is offhand, the 3/8" group is over bags.
Loaded with .25 caliber Nosler 100 grain ballistic tip drawn to .254". Still slowly working loads up and these are at 2425'/sec.

The 2425'/sec took 40.5 grains of IMR4350 with no pressure signs so I will continue upping in .5 grain increments.

May try Reloader 19 at some stage. Hope to get 2750'-2800'/sec to duplicate original quoted velocities.

Truly a "blast from the past" as this rifle possibly has not been fired since the 1950's

As an aside; this rifles first owner was one Ivan T. Sanderson. Quite a character I'm sure......

Hope to get over to Steve's place to pick it up this coming week, depending upon weather.

Marmots.....almost as dangerous as the Monty Python "Killer Rabbit", will have my .577 along in case of a charge.
Right now my shooting spots are under about 2 feet of snow.

Re: Cogswell & Harrison .242 Vickers

Quick update:
Achieved a solid 2837’sec 5 shot average with IMR4350 and 100 grain Speer pointed soft point, no excessive pressure signs.
Standard primer and 47.0 grains of IMR4350.


I wish I could bring myself to fire a couple of my original Kynoch that are loaded with 41.5 grains of whatever they used, I would be surprised if those original loads made advertised velocities

DISCLAIMER:
If you happen to have a spare .242 Vickers chambered rifle sitting around please consider this load safe ONLY in my rifle.

- Mike

EDIT ADDED:
The sights are a standing marked 200 yards and one folding leaf marked 300 yards.
Using nominal velocity and ballistic coefficient assumptions and my altitude of 7500’ I will be looking for 1.3” high at 50 yards and ~2.2” high at 100 yards.
This is to be checked my next outing.

Re: Cogswell & Harrison .242 Vickers

I hope that load is to your sights 3DM, not bad going if you don't mind me saying.
Greta to see good results with your sized pills.......damn fine if you ask me!
Time to use on a white tail or 3!

There is an elegant simplicity in an open sighted Mauser actioned rifle and yours is a beauty.

Look forward to hearing of more adventures with it.

Can you measure the size of your front sight bead when you get a chance please? I am finding front bead size matters as my ageing eyes struggle to see fine beads!

Rockdoc,
Will do that! No kidding about aging eyes.....I just turned 68

Right now the rifle is at Steve Bertram's getting a crack in the wood behind the tang fixed.

Nice rifle that seems to want to shoot well. And a very interesting first owner. Now if only these rifles could talk, as they shared many intimate moments with their owners. Imagine some of the campfire discussions!

Re: Cogswell & Harrison .242 Vickers

Back to top,
Have heard from a member "Hendo" who hails from Australia, says he is in the process of getting a .242 Vickers. As a .242 Vickers owner he will be a member of a VERY small club indeed.

Perhaps he will eventually chime in with details of his rifle and the attendant "pleasures/adventures" () of making ammunition to get it shooting.

Cheers, Mike

Re: Cogswell & Harrison .242 Vickers

Mike, thanks for redirecting this thread. Your rifle turned out very nicely. 100 gr bullet at 2800 fps, wow! Very effective.

It may have been mentioned already. But what is the true calibre of the .242 Vickers? .254, as you mentioned resizing bullets to?


Good news about Hendos rifle. I may get to see it. Hope so.

A .242 Vickers sounds like a nice vintage cartridge and rifle to have. An ideal rifle calibre class for most game in Australia.

Re: Cogswell & Harrison .242 Vickers

PS these need to be added to the unusual vintage calibres/rifles thread.

It is so much cooler to use a .242 Vickers than some unmentionable mass market new wannabe pretender!

The true calibre, ah now THAT is the $64,000 question!

The "bore" may have in fact been planned to be .242", while the groove diameter may have been hostage to various barrel makers machine tolerances in the rifling process?
As I mentioned, my old original ~1930's Kynoch ammunition has bullets of very long taper ogive and a base diameter of .2475"

Various sources claim barrel groove diameter of .249" to .253" while my rifle has a groove diameter of .255"
I don't have proper small diameter plug gauges to actually figure out my rifles true "bore diameter" at the top of the lands.

Sooooo…….I'd opine that calling it a .242 is as good as anything.
I would be curious to know how those original .2475" bullets shot out of my rifle with the .255" grooves with rifling that "may" be only .004" deep?
100 yard "minute of Blackbuck" accuracy? Bullets with thin jackets actually soft enough to slug up a bit in the barrel?
