I was off on the amount of black powder in the 3 dram load. I used 76 grains of FFg. It fit in a AA shell just fine. The dupont powder guy told me that about 83 gr was 3 dr equivalent but that was with card wads. With a plastic overpowder he said to cut the load back a few grains because of the better gas seal. So I used 76 grains. And yes Fabs..80 somethig grains of SMOKELESS powder in your load, if you could fit it in, would blow the gun. It would not be pretty.
