Got out today with the Ballistic Advantage barrel from Brownells in 20. I dropped it into a Larue built 6.5 Grendel and put a new Monster bolt in. Low profile standard gas block and no break. Shot four groups getting it zeroed with Hornady Black all of which were about 1. Kicking myself, I left the Magneto speed on the bench.
Went to the steel range to stretch it out. I plugged 2750 into TRASOL and found at 420, 566, and 720 that impacts were a bit high. Trued it to 2720 and it was ringing steel at 840, 950, and 1090. All of the steel is roughly full sized IPSC. Wind was 16 mph from 120 degrees, it handled the wind well. Recoil was very nice and spotting was easy without a brake.
Ran 50 rounds through it and the groups seemed to tighten up some. Last 5 rounds were at 420 and well under 1 MOA. I didnt bother driving out to measure. I will take the chrono later this week and confirm.
