I shoot mostly 12ga 3/4oz loads. In the 12ga - .729 bore - a 3/4oz load has a shot height of .52, 7/8oz a .60. Both are way better than the 28ga bore to shot height, and even the 1oz at .68 has a better than square relationship. In my 10ga loads I shoot 1 1/16oz loads, and there is no recoil to speak of. I'm now waiting for Bachelder to make a Parker 10ga into a 8ga. Right now it's quite a heavy gun with thick barrels, but will limit my loads when I get it. It will probably be a kind of light gun for a 8ga, and I don't like recoil.
