Cartridges

You have some nice ones there RCS pity the water separates us we could have some good conversations on cartridges I have some pretty cool wildcats that I'll start on after the N.E's as for some ppl it may be the first time they have seen a particular round.
I have one called the "Western Hunter" it was a privately made round submitted to the Police ballistics branch for testing before they would ok it to be legal, as far as I know it is not commercially available Graeme Williams designed it for his top end buffalo hunting business.

I have yet to get a reply from anyone on the roll crimp on the 1944 MW MkVII 303 round I posted in #67.

Well I for one have never seen one like that. But...I don't have many. I've had lots but still never seen one.

Thx for the reply Jim.

Here we have my Rigby .350 Magnum Nitro.

The .350 Rigby Magnum was introduced in 1908 as the successor to the popular 400/350 Nitro Express. Rigby developed this rimless caliber for use in the Mauser magnum length action. No other maker, at that time, offered this combination in a magnum-length bolt action rifle and Rigby’s name became synonymous for the best in Mauser-actioned big game rifles.

The .350 can propel a .358 dia., 225 grain bullet at 2,625 fps with 3,440 ft.-lbs. of energy. Big game hunters began using this caliber on elephant, rhino and buffalo, although it was never advertised or recommended for such heavy game. Rigby’s .350 Magnum became the most widely used medium bore caliber throughout Africa and is still used today on Safari.

“RWS 9.3x82 NIMROD” is c1910-1922 and is probably the commonest headstamp encountered on the 9.3x82R Nimrod.
I looked on the web but its a hard one to find the 9.3 x 74 R is there along with shorter variants of the Nimrod but of the 82mm one very little.
From the little I found its around the same as a 375 H&H but not quite as powerful you do not see to many of them.

Interesting 303, that.

Your 9,3x82mm is quite rare, few around.

the 303 cartridge with special crimp is also not common, maybe a special bullet ?

Here are a few metrics, have post these before

left: 8x72R RWS, 9,3x72N Swiss headstamp M+FA, Brenneke 8x65 RS, Norma 9,3x74R and last is 11.2x72 Schuler. I read omewhere that the 11.2 with the rebated rimless case was first used in the early Mauser riflesAttachment 127973

They say the Schuler is on par with the 458 Win Mag.

This is a reasonably old cartridge probably around WWI vintage 1914 +- !
The lube is gone from the projectile but all in all its not in bad shape being full lead.

The 11.15 X 65R STAHL EXPRESS was slightly less popular than the LK variation of the case length which is evidenced by its production lifespan from about 1885 until WW1.

No 1 manufactured by B Stahl indicating a St type case
No 2 manufactured by B Stahl indicating a St type case with black primer annulus
No 3 manufactured by B Stahl indicating town of manufacture with large font
No 3 manufactured by B Stahl indicating town of manufacture with large font with black primer annulus (My cartridge is of this type)

The 303 cartridge is a little unusual due to the type of crimp which is like a roll crimp instead of stab type as is typical of the service round, does anyone have a clue if they trialled different crimping styles it would be nice to know as there is bound to be some here that may have the knowledge.
I know on 303 WRA (Winchester Repeating Arms. Pic #3) primers had 4 tabs formed over the primer to stop them backing out in MG's in aircraft, well that's the story I got from a cartridge collector friend but anyway does anyone here interested in why they trialed this.
I'll look through my other 303's and see if I can find another like it and as far as I can tell it is a factory loaded round H/S MW 44 VII

My 10.75×68mm RWS, also known as the .423 Mauser, is an obsolete rimless bottleneck centerfire rifle cartridge developed by Mauser and introduced in the early 1920s.

The 10.75×68mm Mauser was introduced by Mauser in the early 1920s and chambered in their pre-World War II magnum sporting rifles.

The 10.75×68mm Mauser was a popular big game cartridge with African and Indian hunters, it was used successfully on all dangerous game species up to and including elephant, although many experienced hunters considered it unsuitable for the latter.
