6mm ARC

[Silverjay]

Ran 20 rounds over the chrono this morning checking SD and accuracy in the velocity node I found. Velocity settled at 2580, SD was 9, and produced four groups of five rounds each just over 1/2” at 100. I think I am done until the Lilja barrel gets here.

I played with some other powders in Quickload and none of them I tried produced a better velocity/pressure relationship. I didn’t have to increase the case volume from actual to get a good velocity prediction.
