Good question Cayugad. I had to pull my folder of targets for the .45 GM/LRH Renegade to see what I've used (96 targets from 6/28/08 to 1/29/11).
It turns out that I've shot mostly GOEX FFFg. But I do have a few targets with T-7 FFG, Pyrodex RS, and Pyrodex P. None with GOEX FFg though. I'll have to try some next time I take that gun out.
I wonder how fast that 110 grain load of Grafs is pushing the Scorpion.
