OK Gun guru's. I have my Dad's older Belgium Browning A5 3' magnum and have a duck hunting trip scheduled for this coming January. Been reading up a little on the use of the current steel shot requirement in waterfowl hunting. Heard everything from it's Ok to don't do it...could split or bulge barrel. Figured a lot of peeps on here that know their stuff when it comes to this.....so let it fly. Thanks in advance.
