I bought a new Benelli 828U in March of this year. I've only put about a hundred trap loads through the gun which, until today, functioned flawlessly. While shooting clays today, the gun has jammed after firing a shell from the upper barrel. The breech now won't open. The spent shell remains in the chamber of the top barrel. Has anyone else had this issue? I have sent an email to Benelli Service and await their response.
