Over 40 years or so of shooting Bullseye competition, I guess I've tried them all but I keep coming back to Bullseye powder. Yeah, its a little dirty but who cares. When I get a new pistol, I always Ransom Rest a variety of powder combinations and let the groups tell me what my pistol wants to shoot. 95% of the time, its 3.7-4.2 grs of Bullseye
