I use Win 231 under Berry's 124 gr Plated. and Bullseye in my .45 ACP. 231 is somewhat cleaner and has less flash than Bullseye. I only keep 1lb cans of each on hand so I don't mind having several types of powder on hand. Win 231, WSF, WST, Alliant Bullseye and Power Pistol. I worry more about primers than powder.
