Lloyd,
Load has always been a few grains of Bullseye. If memory serves..... about 2 grains. Start from there and adjust as necessary. Might need 2.5 grains for the .45 case. You'll most likely stick a bullet or two, make sure each one exits the barrel before proceeding.
I've found a significant decrease in leading. Accuracy - almost certainly some gains, hard to say without someone who is a better shot testing the guns for me. It's never been worse, though.
