Anyone using it? I just bought three pounds and not much data is available yet. Any info on 9mm, 38spcl and 45acp would be appreciated.

I acquired two one pound containers of Win-AutoComp for experimentation usage. Only used in the 9mm Luger to date with bullet weights 124/125Gr. Appears to be clean burning, minimizes muzzle flash, meters consistently with powder measure, and acceptable accuracy at 50 yards. Test bed firearms Glock-G17 and a S&W-MP9.

Relative burn rate bracketed between Hodgdon HS-6 & Vihtavouri 3N37.

www.wwpowder.com for current data.

I agree, the most current data for AutoComp is available on the Hodgdon Load Data Site. They list AutoComp data for all bullets ranging from 90gr to 147gr in the 9mm, from 110gr to 170gr in the .38 Special and from 155gr to 230gr in the .45 Auto.

Thanks, I had seen that data but was interested in more "personal" info and I think Dennis nailed it.
