Khaot1c Posted April 20, 2021 Share Posted April 20, 2021 (edited) I picked up a bit of Shooters World Clean Shot. It is my first time using this particular powder. I had to increase the charge quite a bit to get my velocities to match what others are reporting. Yes I know things will vary from one firearm to another, but these numbers seemed way off the mark... Using a 9mm P320 Legion X5 with OEM barrel - 10 shot test groups over the chrono. Hornady FMJ 115gr @ 1.150 with 4.6gr Clean Shot : Average: 1105 Pf: 127 SD: 10 Blue Bullet 135TC @ 1.125 with 3.8gr Clean Shot Average: 991 Pf: 133 SD: 12 Everglades 147 JHP @ 1.110 with 3.7gr Clean Shot Average: 877 Pf: 128 SD: 10 Does this powder suffer from a wide lot-to-lot variation?

ChuckS Posted April 20, 2021 Share Posted April 20, 2021 FWIW, my PCC has about 8" of rifling before the comp. It takes me 5 grains to get to 1200 FPS. That is with a 115 gr Berrys bullet. I did try 4.5 and it was in the vicinity of 1100 FPS. Your 115 data seems reasonable. I never tried a heavier bullet. Link to comment Share on other sites More sharing options...
CharlieD Posted April 20, 2021 Share Posted April 20, 2021 Could be a little slow, but sounds good enough. It’s important to understand that CS is reverse temp sensitive, so if it was a hot day or you left your ammo in a hot car, then your velocities will drop. If it helps, I use 135g blue Bullets with 3.6g CS, and get 990fps from a Glock 17 (4.5” barrel) on a 70 degree day. When the temps get into the 90’s, then velocity drops to around 965fps.
