Roost em 1st:

Before your buddy wastes his money, see what shells he is using. The Benelli manual recommends using 1 1/8 oz. minimum. I have shot most all factory shells through my SBE and have never had a failure w/1 1/8 oz. loads. However, some of the 1 oz. and a lot of the 7/8 oz. are unreliable. I would have to say that his problem probably lies with too light a shot charge.
