Well, I thought the spring fixed it but I guess not. I shot probably 6-10 caps through it and it did fine. Then I loaded it and shot 3 times without cleaning it fine. Then on the 4th shot it started doing it again. You kept having to shhot twice. I took it and cleaned it since it was pretty dirty by that time. After cleaning it I shot probably 6 or 7 caps throgh it and all but one worked. It's also been rainy and damp so I'm not sure if that made a difference. So what else could it be? I'm at a loss. It seems to work a lot better but not 100%. Would it being dirty after several shots be the cause of this?
