I didn't realize I only had 30rds of 9mm fmj left. It went through those no problem. I also had some old cast 9mm that a friend gave me. I did not like those, but I'm gonna blame the ammo on that one. I stopped by wally world on the way back to pick up a winchester value pack of 100rds. It's gone up from $13 to $19 Oh well, it's still cheap compared to everything except .22
