I used to shoot 1 oz. loads at trap. At the time, I was practicing/shooting with All American Jimmy Walker. I mentioned to him one day that I was shooting 1 oz. loads and he remarked that if you shoot 1 oz. loads, you are beat before you even start. He was right. It wasn't long before I was shooting in the local calcuttas against guys like him and Pat Neff, who has won the Grand and several events there over the years, and was getting my butt kicked. So, shooting less than a 1 1/8 oz. load is OK for piddling around, but when the money is on the line, you had better get some shoot in those loads. I use a 1 oz. load for shooting skeet, now, but when it gets time to be serious, my loads are 1 1/8 oz.
