Range day today so I took along 100 rounds of .45, 230grn. Berry plated and using 5.4gr of Winchester 231. It seems to burn a little cleaner than my rounds loaded with Bullseye however not enough to discourage me from using either one. It is much cleaner than Power Pistol as you use a lot less powder when you use 231 and Bullseye. My groups were in the 3-4" @30' today which is my standard shooting. Problem is I am running out of rounds loaded with W231 so I will have to switch over to Power Pistol and then back to Bullseye. As far as accuracy, I believe all 3 powders to be close to, if not the same in accuracy. I am running a little low on rounds loaded so after the 1st of the year I need to get my butt in gear and start reloading again. That's my report. Good luck on your shooting!!!
