I have a substantial amount of "Clays". I've had good success using it in .40 and .45. Not so much in 9mm. It's a clean burning powder, delivers good velocity, and single digit SDs with all bullet weights I've tried, 115/124/125/147. The bullets have all been cast or powder coated. Accuracy has been nonexistent in pistols with twist rates from 1-9" to 1-16". I've played with charge weights, OAL, and crimp and have not attained acceptable accuracy with any combination I've tried. I'm talking patterns here, 7"-8" at 20 yds. Some combinations even worse. Unacceptable for me. That's enough to miss the "A" on the long shots. I also have a good supply of "Promo" (Red Dot). Using the same bullets, brass, and primers, all my 9mms will shoot into 4" or less at the same range. I should say, I'm loading for a 130-135 power factor, and want to stay in that range. Haven't tried plated or jacketed bullets, as cast has worked well for me and much cheaper at the volume I shoot. I'm kinda at impasse here, anyone seeing something I'm missing here? Any insight appreciated! Thanks!
