Miller, I shot IMR 4227 in a 10 ga. load back in the late 70s for turkeys. It was a 2 1/8 oz. load of shot propelled by 70.5 grains of IMR4227. It was a great load in warm weather, but an occasional blooper of a load in cold weather. It had a reported velocity of 1289 fps with pressure of 10,400. The wad was the 10 ga. Pattern Driver plastic wad in a 3.5" Remington hull. It was published by BP and attributed to Tom Roster but the load disappeared from the BP list of 10 ga loads in a later flyer. Gil
