Not a real big deal, but.. Was shooting Federal 180 grain stuff the range had, no problem. Shot some Winchester Silvertips no problem. Switched over to Hornady 180 grain XTP, and had an empty case hang up with the mouth of the case jammed into the top of the chamber opening. Any idea what could have caused it? Not a huge deal but I am curious. I won't be carrying any Hornady 180 grain XTP either.
