The limiting factor for me, is pistol powder. I can't find them anywhere.
There are lot of powders that work well in the 45 ACP.
My favorites are:
PowerPistol, Unique, Bullseye, SOLO 1000, Autocomp, Accurate No.2 & No. 5, & Win 231/Hodgdon HP-38
Others that will work (& there are still more than I will list)
Universal, Clays, CFE Pistol, SR4756, Titegroup, 700-X, Win WST.
