Thanks guys. I haven't actually dropped the trigger mechanism or pulled the firing pin out yet. I'll probably wait until after hunting season then do that. Is something like CLP the best to use to clean all that? I know you don't want something that's going to stick and gum it up in cold weather.
My barrel definately has a constriction. I don't think I can start a patch from the breech end. The question is, do I work on that with JB's? It would be a lot easier to clean it without having to remove the barrel from the receiver if I could clean from the breech end. As it is now I have to pull the forearm and remove the barrel to clean it. Not that big of a deal, just kind of a pain.
