Standard load for a 28g is 3/4oz. Whether it is no different than shooting 3/4oz out of a 12g, I do not have a clue. I normally shoot 7/8oz out of a BT99 choked light full (Briley). I do better with it with that load than when I shoot any of my 20g guns, choked full. While they may be the same weight shot, I was using different shotguns. My 2 cents.
