I don't believe you can change performance a lot in the way a BP shotgun shell is loaded as far as compressing the BP a little or a lot. You're not trying to shoot a one hole group. You've got a 30" circle with lots of BBs. They may get there a bit faster, but not anything you'd notice. Equal amounts of shot and powder is all that's needed. You'll get a good pattern with decent velocity. Don't try to make it harder than needed.
