Using either Xtreme 124g plated bullets (preferred due to cost), or standard 124g FMJ, I prefer 5.5-6.0g of Alliant Power Pistol. PP is a little hard to find right now and I am experimenting with Shooters World "Major Pistol". It is supposed to be the equivalent to AA-7 but the load data varies slightly. So far, it seems to work okay but I just still prefer PP when I can get it.
