I have a Winchester Model 25, 12 gauge that I got from my Dad when he passed away. It's circa 1950. I've shot skeet/trap with it a few times. So far I have to clean it from the muzzle end because I can't figure out how to remove the barrel. I always put a clean rag into the receiver, but I just hate pushing all that crap and chemicals through that way. If anyone knows how to do this can you post the instructions here?
