Hello everyone. While I may not hunt Africa, and am not currently planning a hunt there. I believe yinz are the most knowledgeable to ask. I currently have a inherited 9.3x57 military mauser with a bent barrel. Someone ran over pap's rifle at the range. He took it elk, and bear hunting, and I'm going to do the same. Im planning on rebarreling it, and figured why not step up a little, I can always down load a bit. From what I'm seeing these two cartridges are darn near the same. Just a hundred or so fps apart. Is that about right, is there other differences, and which would you choose?
 
hmmm
Are you reloading? If not:
Of the two, 9.3x64 ammunition could be easier to find.

Are you planning DG hunt in Africa? If yes:
Of the two, 376 Steyr, will comply in almost all African countries as a minimum for DG.

Take your pick.
 
Do you just want to rebarrel?
the 9.3 x57 is based on the 8x57,
the 376 Steyr on the 8x68
the 9.3x64 is a unique cartridge

very different amount of smithing needed for a change of caliber

the least amount would be to stay with 9x57 or 8x57, conversion to 9.3x62 would be minor gunsmithing and more power, since you reload you could consider also 8x60 or 8mm-06 .

The .376 Steyr is based on the 9,3x64 Brenneke.

A 9.3x57 military rifle? That most likely will be a Husqvarna, in a '96 or '98 action.
A 9.3 x 62 would be a terrific and reasonable, cost wise, conversion.
Not as powerful as the other two options mentioned, however, still with more than enough power for elk and bear.

Yup it has some WW1 german markings on the reciver. I was told my great great grandfather rebarrelled it from 8mm mauser to 9.3x57.
 
.376 is made from 9,3 cases to fit in a standard or was it short action in a Steyr Scout . Devised by Col Cooper . The Scout then was named Dragoon . Bullet was 270 grain . Better it was in a standard action for it . As Hornady is one of very few makers and the Dragoon was dropped short time later .

The Brenneke is above and beyond the call one is looking for then and now .
 
While only briefly looking at some figures:

The 9.3X57 has a base of 11.95mm, as does the 8X57mm. The .376 Steyr and Brenneke rounds are both much larger (12.60mm), so you would have to work on the bolt face as well as the barrel/chamber. The COL for the Steyr is slightly smaller than the 9.3X57, so you'd be OK there, but I don't know how the extra 4.6mm COL between the Brenneke and the Mauser would affect your rifle.

Have a good gunsmith take a look at it. If he says the action is safe, after the barrel getting run over, take a look at the 9.3x62 ballistics. See if it'll meet your requirements.
 
You
you are correct.

still with the starting caliber , I would consider a 9.3x62 for rebarrelling. so much less work than a x64
You are correct
9,3x62 is perfect for a M98, easy to shot and come by, and powerfull enough.
