Thread: Suppressors with corrosive ammo

I've put over a case(1250 rnds) of norinco steel case steel jacket through my Howa with a dpt muzzle forward can. I had a small amount of corrosion once due to my leaving the can on for a bit. I do know better but was distracted ,white stuff growing on the first baffle, ended up as light pitting. I usually spray with crc long life and leave in the sun or hwc and it's never happened since. The ammunition is quite dirty though and I agree the labels confusing non corrosive primer or case, or both.
My experience leads me to believe it means the primer.
