I never saw any need to do anything different than equal volumes of powder and shot. If I was on the bird I killed it with that load. I favor 7 1/2s with a m/l for doves and quail. Equal volumes do not yield high velocities and the extra mass in the 7 1/2s pays off in more dead birds as opposed to cripples, in my experience.

When shooting skeet, or some other clays game, soak the fiber wads in some moose milk. It will significantly reduce the fouling build-up, between shots.
