Hi-Power Jack Posted June 5, 2014 Share Posted June 5, 2014 Have some 124 gr MG JHP's and some Winchester Auto Comp powder (WAC). I saw Jman's note that 4.5 gr WAC with moly Billy Bullet hit PF 133 - anybody have any chrono date for WAC and jacketed 124 gr bullets. I'm loading at 1.135" for a Browning Hi-Power 9mm. Trying to reach PF of about 133?? thanks, Jack Link to comment Share on other sites More sharing options...
cecil Posted June 6, 2014 Share Posted June 6, 2014 I shoot Montana Gold 124 CMJ bullets seating them 1.16 COL ... using 6.0 gr Auto Comp... which makes 148 PF Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted June 6, 2014 Author Share Posted June 6, 2014 thanks, Cecil, that's a start. Now need to get it down to PF 133 - guessing it will be little below 5.0 grains. Link to comment Share on other sites More sharing options...
Toyotafrank Posted June 6, 2014 Share Posted June 6, 2014 love Auto Comp if I could just find it... Link to comment Share on other sites More sharing options...
Sarge Posted June 6, 2014 Share Posted June 6, 2014 I loaded some minor loads with WAC using MG 124 CMJ's. I made 130+ with 4.8 at 1.13ish out of a 5.25. It was a little dirty and kind of harsh compared to 231 and 320. But it did work just fine. Link to comment Share on other sites More sharing options...

Sarge Posted June 6, 2014 Share Posted June 6, 2014 Sounds like we have it pretty well bracketed. Now it will be up to your gun, Jack. Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted June 6, 2014 Author Share Posted June 6, 2014 (edited) Thanks, Gentlemen - just tried 4.5 and it fed reliably at 1.136" OAL and reasonably accurate - have to break the Chrony out, now.

Sandbagger123 Posted June 6, 2014 Share Posted June 6, 2014 i have tested some in the past. what i found interesting is that it seems to be a twin to WSF in load and velocity even though its listed as a slower powder Link to comment Share on other sites More sharing options...
