well ok u got my i reload alot and there hot (not that i wont share but i think i might bore you with the specks of the rounds i load)"i am getting 2" groups at 500 yards give or take a yard"
Gnoll, I ain't saying that's not so, haven't seen your targets nor your 500 yards but that's a LOOONG shot for an assult rifle cartridge. Don't know if you're shooting factory, surplus mil or hand loads but for most full charges in that cartridge it will drop about 5 5 1/2 feet at 500 if the sights are zeroed at 200! Wow.
And a 2" group at that range requires (1) about a 3/8" group at 100 yards and (2) absolutely no cross wind and (3) a target grade trigger and (4) high grade optics to even see how to shoot such groups.
Very few high quality bolt action .30 cal. target rifles shooting high velocity cartridges that have been precision loaded with target grade bullets can equal the accuracy of your Russian 7.62x39 Saiga. You need to treat that thing with kid glooves to preserve such an exceptional rifle from any damage that will bring it back to earth. And stock up on 10,000 rounds of that awesome ammo too.
