Accurate powder meters well, too, ball type. At least #9 does. It burns clean, too. I might should try some number 2. I'm pretty standardized on bullseye and unique for .45, but they are a little dirty.
I found that using Alliant Power Pistol for my .45acp reloads works great.
For my target loads, I use 230gr FMJ/HP's (When they odn't have FMJ cheaper ;D),
and using a 5.5gr load of PP, it works great. Very clean burning powder,
nice flash ;D, and little recoil.
I have not done any REAL accuracy tests with a pistol rest, but off hand from a kneeling position,
at 10 yards I can get sub 2" groups if I do my part from my pt145.
Slightly smaller with my Charles Daly 1911 Govt model.
For a normal 230gr load I use 6.6gr of PP and it equals the remington's recoil.
