What does knowing the history of the 3.5 have to do with my post? The OP asked a question and I gave him the results that I have found in my Benelli. The 3.5's would not produce the patterns that I fell are acceptable and always gave me numerous fliers even after I had the forcing cone lengthened, but the 3's always gave great patterens. I called Winchester and discussed my issue and posted what the rep told me, this is not my opinion just what a Winchester rep said. How did the topic go from predator loads to steel shot loads for birds?
