4 shots at 600, 3 of them in 7/8"
Went out yesterday to verify drops as far as the scope had travel. I had verified drops to 800 during development and Ballistic AE showed velocity at 2965 fps when entering all pertinent info.
Shot a group over the chrono. Average was 2965 with an SD of 3
Used that data to to make multiple impacts at 1580 yards in 13-15 mph cross wind. 2 mils
The 9 twist causes no degradation of BC whatsoever
