So far I have only used PMC's fmj rounds for target practice with my .40 cal. I have shot 150rds through it so far and have not had one single issue. Every round has fed, fired, and ejected properly. Does anyone else have any experience with their ammo? Seems pretty great so far. I have bought the 50rd boxes at big r and they sell for $20 there. So thats $0.40 per round, doesn't seem to bad to me.
