So I should have noted I'm using small winchester magnum primers, I've always heard that's maybe 15fps, but I haven't ever actually checked that. I chronoed about 6 different loads, and found that 4.15g and 3.92g were the closest. The FPS for 4.15g was avg 942, with a good spread of 959-931. 3.92g yielded an average of 916fps, pretty big spread on just two shots from 951-896. Through some intense calculations, I fond that 4.05g should give me pretty close to 930fps average, so keeping even the lower shots right at the min point. I'll be loading that up this week. Anywhere between 4.05g and 4.1g should be fine if I get lazy.
Chrono was done at 10 feet, STI 5" factory barrel, 180g blue bullets, 1.183 OAL, and Alliant E3 powder. Thanks everyone for your help!
