Hi all I drew a permit for fall black bear this fall. This will be my first time and I am going with an experienced friend. My question is this: I customized a couple of old rifles; a Yugo Mauser and a Nagant carbine. Will the 8mm or 7.62X54 rounds be sufficient for use on a Blackie? or should I use this as an excuse to pick up a 45-70 ( one of my fav. rounds) or the old trusty 30-06? Thanks Russ

The 8mm mauser will do fine on black bears.If you are going to be shooting 150+ yards might wanna get the 06.

Any of those choices are more than adequate for black bear...

If I were you I'd use whichever one I felt most comfortable with...

Use the 45-70 or the 30-06, not that Russky Commie stuff.

If you'll kill bear, use the all-American classic. 8mm Mauser, though, is an American spoil of war, and seems to be a nice cartridge.

I agree with Pygmy, I think all of them would work, but I'd lean towards the 06' or the 8mm.

8 or 7.62x54 is plenty for bear. good luck.

either would be fine, I would probably go for the 8mm myself.

I would use the 7.62x54. BECAUSE I have one.

Load the 7.62 x 54 up with 180 or 220's. Should have plenty of gun. Plus you have the satisfaction of using a piece of history and not just some off the shelf unit. I had to buy another one after my wife took a Ram from 180 yards, and claimed that rifle.

My mind is definately goin but isn't the 7.62 by 54 the old NATO round? Know to you as the .308.
More than enough for any blackie.
