What I find troubling about the Hammer Double load is the amount of powder used. My IMR 7625 load is WW209 primer, AA hull, 22.5 grains powder, CB1118-12 wad and 1 1/8 oz shot yielding 1145 fps @ 6500 psi! I don't know the difference between the friction in a brass hull compared to plastic, but I would not start with 30 something grains of powder in a plastic hull and fiber wads.
