Tried another 9mm load with BE-86, 6.0g and pulled Federal HST 124g loaded to 1.130" in Federal brass with CCI 500 primers.
In a 4" barrel: 1135 avg, 1154 high, 1124 low, 11 sd
In a 3.4" barrel: 1108 avg, 1119 high, 1094 low, 12sd
Accuracy good enough for me to keep dinging a 4" plate about 10 yards down from the chrono. A little bit of primer flow, so it seemed like that was as hot as I should go. Speer shows 6.0g with 124, but Alliant only shows 5.8.
I checked some factory loaded 124g Federal HST and the stuff I have on hand was loaded to 1.100"
I ran some last year and got:
3.4" barrel: 1121 avg, 1144 high, 1098 low, but I only put 2 rounds across the chrono so the SD number is kind of meaningless.
