I buy bulk, too. Got some milsurp Winchester stuff and stocked up on Bullseye, Unique, Varget, and some CFE. Not enough to require a purpose built magazine, tho.
Buy cheap, stack deep. Right?

I actually became very fond of Scott Powders, and had great luck shooting pins using "Royal Scott" in both my .45auto and .44mag pin loads.
