You can run basically any 7.62x39. I think the Riley Defense AKs are even chrome lined which allows you to shoot the crappiest, most corrosive ammo out there. Just buy what's cheap and clean your gun.
Those have sadly gone up in price where I live. It's like 70 cents a round ugh.For indoor restrictions, Bellom (Serbian) has run excellent for me...seemingly on the cleaner side too.
For $1-$1.50 per round? Yikes.If you’re looking for a good hunting load, Hornady black SST is awesome! In general I wouldn’t pay more for brass case unless you plan to reload. I will just shoot whatever is cheapest. the one and only Ammo type that I have ever had a dudd is tula. If you’re looking for something to stock up on anything that is laquer sealed cases will be fine.
