I can't say for sure yet, but I will have data within the next few weeks. My gut tells me that it is, since it's a ball powder, but I don't have evidence yet.
Here is a 20 shot chrono string of 25.2gr under a 69gr SMK. Temp when it was shot was 21 degrees F. 1)2701.0 -7.2 2)2715.0 6.8 3)2716.0 7.8 4)2700.0 -8.2 5)2726.0 17.8 6)2720.0 11.8 7)2722.0 13.8 8)2733.0 24.8 9)2702.0 -6.2 10)2722.0 13.8 11)2712.0 3.8 12)2720.0 11.8 13)2706.0 -2.2 14)2694.0 -14.2 15)2699.0 -9.2 16)2713.0 4.8 17)2693.0 -15.2 18)2719.0 10.8 19)2677.0 -31.2 20)2674.0 -34.2 High:2733.0 Low:2674.0 E.S.: 59.0 Ave.:2708.2 S.D.: 15.3 95%: ±7.5 |
