What is CLP and what is half mooning? Thanks. I have a 10 year old SBE and a new SBE II that seems to suffer from some of the maladies I see on this forum. It doesn't send a shell up after the first shot and will put a crescent indent in the brass. I replaced the spring and plug in the shot tube with stainless and a little better, but still jams. I'll try lubing the back spring and see if that helps. Any other advice appreciated.
