First efforts with milsurp powders

[Hutch]

Guys, I am a bit surprised by my first results in loading .30-30 cartridges w/ WC844 and WC852f. It appears that the velocity I got was higher than I expected, as measured by chrono. No visible pressure signs (no cratered or pierced primers, no indications of sticky extraction, etc.)

Winchester LR primer, Hornady 170gr FP bullets, Marlin 336

34.0 of WC852f ==> 2177fps Avg, 7.5 SD
31.6 of WC844 ==> 2220fps Avg, 17.5 SD

I selected the charge weights based on H380 data for the WC852f, and H335 for the WC844. Predicted velocity was 100 or so lower. Am I too hot? Accuracy was nothing to brag on, but I may have been having a bad day.

On a reassuring note, I also had the .357 carbine out, shooting both H110 and WC820. It looks like the WC820 loads like AA #9.

CCI SP Mag primer, Hornady 158gr XTP, Marlin 1894C

14.0 of WC820 ==> 1634fps Avg, 17.0 SD
15.0 of WC820 ==> 1758fps Avg, 19.2 SD

No pressure signs. I think I'm gonna warm these up, and make sure they don't go in my S&W Model 60.

I have used all of the ones you listed, they work well. The WC852F proved to be just a little faster burning than H380. I blew some primers working up loads in a couple of cartridges before I reached the H380 charge level I had been using. All in all, good powder at good price. GOOD SHOOTING!!!!!
