I shoot thousands of rounds of Wolf and Tula a year. Since 1998 I've only ever had 4 problems. I shot it in Lugers, 1911s, AKs, ARs, Glocks, CZ, Sig, Remington,....that's just what I can remember. Yes they are dirty but why do you clean your gun to begin with? I hqve cases of this stuff. Only thing is I've never owned a 380
