3 different loads evaluated. I specifically loaded up some 4.5grain rounds to run this test. The test compares 3.5, 4.0 & 4.5 grain loads. Other than powder throw, everything else is equal: 165 Rainier RNFP bullet, Federal brass (multiple firings), Winchester WSP primers, Hodgdon's Titegroup powder.

I pulled quite a few newb moves with the chronograph, like not resetting between 3.5 and 4.0 loads, but I went back and did the calculations for average. Stay tuned as I continue lower until it either doesn't cycle the slide or get simply get too much unburnt powder to want to continue (same goes for accuracy). At self-defense training distances, 3.5 grains is VERY accurate (more so than my sloppy trigger pull).
