I've never used VLDs before, so I am following the Berger method to find a good seating depth.
I have a Krieger barrel for my 6.5 creedmoor, and with previous bullets (ELD-Ms) I was able to get 10 shot SDs anywhere from 3 to 8 with my current load for ELD-Ms.
Being new to VLDs, I tried a seating depth of jam which was a bad test because the brass still had to grow. I had SDs for 4 shot groups (which to me is statistically insignificant) of: 5, 13, 14, 18, 21.
Tested today with once fired lapua brass, bumped .002. This time I had a seating depth of .079. My SDs were:
8 (for 5 shots)
17 (for 7 shots)
18 (for 7 shots)
12 (for 5 shots)
The above is about where my node is. I'm curious if standard deviation will get better if I find a better seating depth for the VLDs.
