All I use are my 3/4oz 12ga reloads at 1275fps. Get a clean burn and the higher velocity is suppose to eliminate a hot center core in the pattern with 3/4oz loads. There's no recoil and they break clay birds just fine. #8's are good for skeet, trap, and SC's. 8000psi is fine for any barrel. I think you're gonna like them. I'd buy some but I can reload 3/4oz shells for about 3.45/box. Good luck - Paul
