I have also had the problem with a brand new benelli, sbe II. I also broke mine in correctly and it cost me a great hunting trip in Canada. I will be sending mine back to benelli for them to fix if they can. The local dealer has already replaced my extrator plate on the inside of the barrell and that did help a little. We all need to call or send them back so they can fix the problem...my sbe never had this problem.
