I have been running my USPSA load as follows for production: 9 mm - 124 grain FMJ 4.2 grains of Titegroup OAL 1.13 I had figured based on others comments and the reloading manuals that this would produce approximately a 127 - 129 power factor, giving enough safety margin to always be over. But at a recent match, they had a chronograph setup and my load chroned at 1103, 1105 and 1106. Meaning my load is running a PF of 137. Based on this I think I can drop my powder to 4.0 grains of TG. I know that this is just one data point, but I am looking for some input, what say you? Thank you, Billy Ray Wanna kill these ads? We can help!
