I second what instinctive shooter says about the 1 oz load. I load almost the same load only with a Claybuster windjamer wad and 18.5 grains of Clays powder and can consistantly crush targets at all clay games with ease. I have even broke trap targets at 37 yards back. Thats a bird out at the 60 yrd distance. Not hard breaks, but dead targets. It only takes about 3 or 4 pellets to break a clay bird. The only time I change is with Sporting Clays if I have long rabbit targets . Then I switch to 1 1/8 oz of #7 1/2. It does take more then 4 pellets to break a rabbit target.
