I am in the process of getting a 9.3x57 Mauser. I read the article in the blog. It is a help and will get me started.

Does anyone have casting and reloading experience with this cartage?

Thanks in advance.

Thanks Wilderness. I didn't think about paper patching. The Velocity is about what I'm looking for. i'll give it a try

Thanks,

That is on caliber that I've always wanted to play with but never had the good fortune of owning one. Congratulations and good luck.

I have a Husqvarna model 46 in 9.3x57. I have a lot of jacketed bullets and don't shoot it much. A shot or 2 a year in hunting season so I haven't went down the cast bullet road. I do think there may be a lot of potential there considering the velocity of a jacketed bullet should be rather easily obtained with cast. I'm mostly posting to say the dies I have, Hornaday, excessively resize the case neck and I would not get another set of those dies if that how they are all made. I am planning to lap out that neck if I ever run out of factory loaded shells. Just a heads up to check if you buy Hornaday brand 9.3x57 dies.

kootne,

Thanks for the heads up. The rifle came with Hornady dies, so I sure will be looking at the over exercising of the case neck. A lot of times I don't resize cases for use with cast bullets.

Thanks,

We ( the Bullshop) have had 9.3x57mm ammo and bullets available for quite some time. I have designed a bullet specifically for the cartridge. Our bullet was designed for hunting and has proven quite effective . It is a 275 gran wide flat nose gas checked design. I hesitate to say here what our load is that we have regularly available on an on line auction site but I will say the powder we use is IMR-4895 and it pushes our bullet to 2100 fps. As for brass we simply neck up 8x57 brass.

I've cast, reloaded and hunted with the 9.3x57 for some time. When I first got it I didn't have moulds and jacketed bullets were pricey. I cast pure lead cores in a 358 core mould. Used CH/4D 358 swaging dies to produce various weights. Made plain base, gas checks, 1/2 jackets and 3/4 jackets, then paper patched them. Really impressive on deer. Of those, the gas checks and 1/2 jackets shot the best and performed the best on deer. Lot of work. Then got a 270 & 300 grain Mountain mould and a couple NEI moulds (290 & 335 grain). Took a while but I also located a Lyman 366408 mould and use that as well. I pushed all bullets like I would a jacketed bullet using IMR 3031 in Norma cases (correct headstamp). Now I mostly use the 270 grain flat nose bullet on deer with complete satisfaction. Accuracy on par with the paper patched and a lot less time.
