A friend has a 9.5x57 rifle and no brass. He does have some 9x57 brass. I'm not familiar with either caliber. Could the 9x57 brass be necked up to 9.5x57 by simply running it through a 9.5x57 resizing die? Is the brass the same except for the bullet diameter or are they different?

Thanks

The 9.5 is larger at the shoulder, meaning, it tapers less. Let me check, I have form dies, and made up a pile of it at one time. I can always send you some.

I found it easiest to start with 30-'06 brass, as that way you can tailor the headspace to your particular chamber. That does require a fair bit of trimming to reduce the length from 63mm to 57mm, but the headspace issue made it worthwhile. 35 Whelen brass would be even easier if you happen to have some as the necks wouldn't require opening up so much. With either, do most of the trimming first, then open the neck. No special forming dies needed, just use the 9,5x57 FL die.

I found the same thing bpesteve, my buddies 9.5 mann has the shoulder nearly a quarter inch foreward of my mauser. I made them from 06 brass and adjusted accordingly.

Back40 - If you can spare some it sure would be appreciated. I'm going to load them for a buddy who just wants to try out one of his old rifles. We don't need that many 10 or 20 would be fine.

No problem, send me a PM with your address and I'll send some out.

When I had my model 1910 I used 30-06 + 8 MM brass, both of which I had a lot of. Remember to trim to length. Also if you cast, the Lyman + RCBS moulding blocks for .375 are perfect.

Back40 - Thanks again for the generous offer. Saw my friend yesterday and he told me he discovered some 9.5x57 brass in his brass stash. Sure wish he would have done a more extensive search before asking me if I could locate some. Thanks again to everyone for the great information on forming brass for this old cartridge.

Hey, it got discussion going about a great old round this way.
I'm such an odd duck I built a .400/375 belted nitro. Got the reamer, dies, a belt forming die so I didn't have to rely on 240 wthby brass and all. It pre dated the 9.5x57 aka 375 rimless by a few years, but is the same thing in terms of ballistics.

Ive come up with some duzzys over the years, one I really liked was a 9.5x63 (9.3x62 case necked up to .375) Got me an easy 2600 FPS with a 300 Nosler..

Another was a number of years ago when bullets for a 450-400 double rifle were hard to come by so with the help of Rick Stickley I built my first and only double rifle on a browning double and had it hardened..The bullet I used was the Remington 416 bullets..It was a 450-416 N.E. double rifle and sent a 400 gr. bullet down town at 2150 FPS or a bit faster..Sold it to a gent who wasn't interested in the custom made RCBS dies for some reason that never made since to me..I still have those dies if anyone is interested, they cost about $200 back then..I'll sell them for $50.00. surely their collectable!!..

I have a 9.5X57 Mannlicher Schoenauer and I use Norma 9.3X57 brass which is commonly available.

The drawing show exact same head space on shoulder with the Norma brass 9.3 having more taper.

I just loaded 15 gr shotgun powder and 2 squares of toilet
paper to fire form the brass.

I ultimately decided the 9.3x62 is the crown mother of the 98 mauser..and doesn't require a lot of changes..I like it as much as my .375 H&H on buffalo, and its one heck of a elk rifle, albeit I have been leaning to the 338 Win for the last few years..If Ihad a good x57 of what ever caliber, I would always opt for the 9.362 rebore or new barrel.

Ray: So you slightly exceeded standard .375 H&H velocity with a 300 grain bullet (2550) with a case which is a tad bit smaller than the .30-06? Isn't that 36" barrel a bit clumsy to handle in the field?

fire form 30-06 cases ...

If you have not noticed by now Ray's rifles always achieve higher velocities and better accuracy then anybody else's.

It is just a fact of that we have to live with.
