I just recently got a used Benelli M2 with a 26" barrel. The gun was pretty much only used a couple of years for ducks hunting. I gave it a good cleaning and borrowed a friends pure gold .670 and went to pattern it with 3" magblends, and 3" hevi 2oz #5's. I'm planning on shooting either the magblends or #6 shot.
Anyway the best I got was 102 in the 10 at 40yds with the magblends. I was pretty disappointed and wanted to know what chokes you guys with experience with the M2's have.
Thanks,
