Since it works perfectly running the action by hand, it sounds like you have a slow shell once in awhile during the speed of the action movement with a fired shot. jzoo: Anything that moves or there is friction, I have some kind of lube on it. I use several different lubes and Tetra Grease on some parts. It depends on the firearm and the part. JP: I'm not on the computer very much anymore and haven't been on here for quite awhile. This is Running Wolf. It's a long story why I'm PM. But I thought I'd give you a shout.
