My main defense load for my shotgun (18.5" barrel) is 2 3/4 inch buckshot (nine pellets) a friend of mine say's I should use 3 inch magnum shells. I understand the magnum shells have somewhat more power, but I think regular 2 3/4 inch will get the job done just as good, and with less recoil. I would like to hear what you guys think.
