Are you a .45 guy like me, or do you prefer one of the others? Also,what is your most accurate load? I used to load revolver calibers like .38 special, .357, .44 mag, and .45LC. These days, however, I find myself churning out .45ACP most of the time. I think I'm going to also get back to loading .45LC, because I used to love shooting my Smith & Wesson model 25-5. Legendary gunsmith, Teddy Jacobson, did a trigger job on it several years ago, and I never shot it. It's time to tool up the 550 and get to work!
