The Russian cheap ammo for those Mosins will mostly go BANG and will throw a nice ball of fire - but if you want to use these rascals for sport hunting look for some Prvi Partisan (former Yugoslav, currently Serbian) hunting ammo for these bad boys. Other companies make hunting ammo for these, but this Serb stuff will get 'er done for $15/box or thereabouts, expect to pay double for US made.
These rifles will ALL have 'frosted' barrels from firing Russian ammo w/corrosive primers. Them's the breaks, that's just how they all are. I shoot Russian ammo all the time, but I carry a bottle of windex to the rifle range and swab out the bore w/windex before I come home, it'll knock out a lot of the corrosive 'salts' that their primers throw out. Come home and clean 'em, they'll serve you well. Good deer rifles, and proven pretty rough on Nazi's too.
