In IDPA I use 3.9 grains bullseye, with a montana gold CMJ in 124 grain. Runs at between 125,500 and 127,000 power factor depending on the weather. Clean burn no smoke, and I can hit a triple tap shoot with a 1" grouping in less than a second with my Sig P226, my Springfield 1911 9mm and my wife's XD.
Seems like a good load.
Thanks zac.
