A neighbor and I were shooting our TC BD's today - about 25 shots each. I was using Pyrodex and he was using 777. I did loosen and tighten my breech plug every 5 or so shots and had no trouble taking it apart for cleaning. He wasn't doing this with his and it's stuck pretty good. He held onto the gun and I tried getting it out and it wouldn't budge.
Any ideas for getting one unstuck?
