Anyone here use Wilson barrels

[SDW]

The first is 26.8 grains, the second is 27.0, the third is a composite overlay of the two targets. The group height is only .108 on the six shots. If this was going to be shot at 100 - 600 yards I would stop right here but at 800 + the velocity is iffy for electronic targets after 600 yards so next session I will be testing 27.9 - 28.9 to see if I can find a node with about 50 to 100 more FPS. I will update once I do the next test and try and do some 600 - 800 yard groups

To add to what I was saying, my loads (123gr ELD-Ms over TAC) in the target below begin where your first test topped out. At my max load here, 28.2gr, had an average-V of 2467, SD of 10.2 (through my 20" BA barrel). I figure you should be able to add 100+ FPS to your velocities pretty easily. Just and assumption. You are using different bullets and I don't know how much that affects velocity here. Another variable I just thought of is, we're using different chronographs. So that's another unknown. My Caldwell seems to have good and bad days for some reason.
