I have an original '87 with a 12 gauge 32" barrel, and it loves BP! I load 75 gr. FFg GOEX the usual fibre and card wad column and 1 1/16 Oz of shot. I cut my plastic AA Winchester cases to 2 1/2 and roll crimp 'em, and my MagTek brass cases are already 2 1/2" long. It's deadly on birds - clay or live.
