For years I loaded 32 grains of 540, a graphited Remington live bird wad and 1.25 oz of hard 4's in a blue majic hull. We cronographed it at 1450 fps and it would shoot through a mallard at 60 yards. Patterns were super. The things that made it work were graphite (speed) and the live bird wad. The fingers were .25 longer than a AA red. I believe it is gone.
