Saw the thread below about the 1891 rifles. I was curious if anyone here would be interested in some as sporter actions. I have a few rifles that the barrels are toast and instead of parting them out, thought some folks would like them for sporting rifles.

What chamberings are safe for the '91?

lc

250 savage , 257 Roberts , 30-30 ( cut the rim ) 25-35 cut the rim , 45acp single shot , 300 savage ( I think still made ) 7.65-54 argentine , 6.5 swede 8 mm Mauser ( us loading screen only ) 35 Remington .

Maybe also .450 Bushmaster. It has a .473" rim and is a 40,000 psi cartridge. Perhaps a knowledgeable gunsmith will weigh in to confirm or deny that as a possibility...

35 Rem; I do like the 91 for those.

I agree, you got me at .35 Remington.

What's the problem with the 7.65 Argentine other than availability?

Absolutely nothing wrong with 7.65 Arg. Except it is a boring 31 caliber cartridge and changing calibers on old rifles is more fun than leaving them alone. Brass is easy to make from 30-06 if you can't find any.
And I have actually fired hundreds of 308 rounds from them; you get a long straight case when you are done.

Absolutely no problems with the 7,65 cartridge, it's a really good one and easy to make even if correctly headstamped brass were to disappear completely. If a person has an 1891 or 1909 in 7,65 with a barrel that shoots well, I can see no good reason to rebarrel it.

That said, my already sporterized '91 needed a new barrel and .35 Remington is perfect for that action in my eyes.
