Gents, I have an M44 Mosin Nagant. It is a lot of fun to own and shoot, and show off and stuff. For antelope season (starting Oct 1), I plan to take it out west. This is not my antelope & mule deer gun, I have some other gear for that. But for prairie dog, and plinking, I figured I might break this old piece out and give it the go that it is itching for. AMMO: I have Bulgarian light ball (157 gr I think), Berdan primed. But with the Berdan, I figured I'd be under too much pressure to clean up the gun right away. So I bought a load of Brown Bear 157 gr. Boxer primed rounds. Got the lighter ammo because of the distance we're firing in Wyoming. 300/400/500 yards. Your expert opinions on this - what am I in for, what are experiences? Also, finally found tracers for this gun on http://ammunitiontogo.com/. The weight of the bullet is not spec'd, but if I can get the tracers in 157gr, that should be a help - no?
