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
