So my story is... Ive owned an CZ858 for about 5-6 months now , i purchased it from CanAm with 1200 rounds of norinco NON CORROSIVE which i ended up going through the case. no rust. So Canam ran out of ammo and i ended purchasing a case from another supplier who advertised as non corrosive and after ONE week this what happened.
Thanks for any input!
