I pulled the above URL from a sixgunner post discussing 20 ga. loads for grouse hunting. I shoot a 20 ga. (Rem. pump, bored modified) using #7 1/2 shot for grouse. Usually, I let the bird put some distance between us before pulling the trigger - otherwise, I too get a lot "less" edible bird. Enter the polywad - supposedly, it will make a modified bore shoot like an improved cylinder. Would this wad with #6 shot make for some good grouse loads?
