Range test of 95 Sst loads today, using Lever, seated 2.185. 4 rounds each charge.
29.6, 2735 sd 1.7
29.8, 2767 sd 10.3
30.0, 2783 sd 17.2
30.2, 2813 sd 5.4
Groups, with the mgsp attached, the 30.0 was best but 30.2 was still pretty good, had some lateral spread I think was me, the vertical was under 1/2". No swipes that I could see.
So I'll do some groups without any chrony attached to see how they group, 30.0, 30.1, 30.2. I don't usually do it this way, preferring to do OAL delta's but I don't think there's a lot of room to vary this bullet in or out in this chamber. I think it will wind up in the 2.180-2.190 range for length, but in all a MV of 2780-2810 is the place I wanted to be.
