I would like to ask if anyone has used or heard about the brass cased alllegedly Bosnian 7.62x39 ammo for sale at The Sportsmans' Guide? They 'say' it is 'match'. I wonder 'cause I know the difference it makes to use real match grade ammo in my bolt .308s -vs- surplus and wonder what this stuff might do for group size in my AKs and SKSs. Anybody?
