A 3" or 3.5" max oz of #8 or #9 shot is dense. That's a lot of pieces of shot. 2oz of #8 is 820 pieces, #9 is 1170! If you can load a 3.5" 2 1/4oz of #9 that's just over 1300 pieces of shot!Yes sir, that’s next in my load testing. I’ve been loading 1 1/4 oz 7.5, but I was checking my wad inventory yesterday to see if I have any WAA12SL to try a 1 oz load.
