heck the way i see it corrosive ammo is probably better for the rifle because then you have no choice but to clean it i was using Hungarian (claimed non corrosive) surplus ammo pretty steady when i got my sks then left it without cleaning when i went to school for a couple months and came back to a chamber so rusted that when i went to shoot it the cartridge got stuck in the chamber and did not even let the bolt carrier go all the way forward i had to clean out the rust with steel wool
