I received some Staball Match for the 6mm arc. My initial impressions are that this powder kinda sucks for 6mm arc 100+ grain projectiles.Velocity was meh. Sd's were meh and accuracy varied from .5 to 1.2" 5 shot groups. Hornady brass, rem primers, 105 match burners. With same components but using leverevolution i gain 200 fps, low sd and .5- .75 5 shot groups. Was hoping this could be a bridge between varget and leverevolution. Sadly varget is better in every way based on todays test. I loaded from 26.5 to 27.5 grains. 2350 fps to 2475 fps. Never hit pressure in any of the loads. The data out there is limited but i ran it up to the listed max charges i could find. My magnetospeed was acting up and missing shots often. Temp was 30* and it was snowing hard. I need to re-test again as i pulled a few shots and my chrono was playing games. Took some hasty data. The trap guys were at the range and i had to stop/start shooting at random times (hate my range at times).
