pskys2 Posted April 26, 2023 Share Posted April 26, 2023 Clays or claydot work great. Tried titegroup and it just heats up too quickly and too much. Cfe is pretty slow burning for a small case and minor pf I think, but I've never tried it. Link to comment Share on other sites More sharing options...

Squirrel45 Posted April 26, 2023 Share Posted April 26, 2023 Iv run WST, No.2, competition, bullseye, 700x, nitro all with no issues. I'm in the mind set that the pressure might be to low w 38sc and get a lot of unburnt. Sport pistol probably will work fine I bet Link to comment Share on other sites More sharing options...
MikeBurgess Posted April 27, 2023 Share Posted April 27, 2023 I'm sure it will work fine, CFE is reasonably clean powder yes its slower than we tend to go for but really in the end it likely wont matter enough to notice after the beep. years ago I was messing around with 170 grain bullets in 9mm and was a bit scared of using fast powder so I loaded them with Blue Dot. they ran fine and were not even noticeably dirtier than normal loads Link to comment Share on other sites More sharing options...

pskys2 Posted April 27, 2023 Share Posted April 27, 2023 Well for uspsa you have almost 200 f/s to go, icore about 100 f/s. So it could clean up a bit. Link to comment Share on other sites More sharing options...
MikeyScuba Posted May 1, 2023 Share Posted May 1, 2023 231/hp-38 is a whole lot cleaner than N320. A fortunate accident of misplacing a few tubs of N320 forcing me to change powders. Link to comment Share on other sites More sharing options...

MikeBurgess Posted May 1, 2023 Share Posted May 1, 2023 some fun math that may help you. current load / current PF x Desired Power factor = new load 3.5/101=.0346... x 130=4.5 grains math is cool and you can tell that the CFE is very linear in this range using your data 101pf /3.5grains =28.857... x 4grains = 115.42PF only off by 0.58 pf from your test Link to comment Share on other sites More sharing options...
