There has been a bunch of discussion lately about seating depth for Berger bullets.
I decided to run a test so I could post a pic of what it looks like. I took my savage 6.5 creedmoor which is stock except an aftermarket B&C stock. It is the weather warrior with 22" thin sporter barrel. BTO on the 140 VLD is 2.210.
Starting at top left 2.220 then top center 2.180, top right 2.140, bottom left 2.100
the bottom center was for foulers and the bottom right was confirming zero on a different rifle so those two are not included in the test.
I shot these round robin every 4 minutes while I was shooting another rifle every 4 minutes so every two minutes I took a shot with one rifle or the other.
I just picked 41 grains because I knew it would be a light load and didn't have to worry about pressure with the jammed loads. 41 grains is just a number, no load development to arrive at this charge just a nice round number.
The chrono readings were as follows from the pro chrony, I don't totally trust it but it gives a good starting point.
2.220 2693, 2737, 2704 ES 44
2.180 2690, 2682, 2688 ES 8
2.140 2672, 2688, 2645 ES 43
2.100 2640, 2693, 2645 ES 53
Anyway this is a pretty good example except I only need to confirm that 2.180 is the best. Normally I would pick the best then seat on both sides .005 or .010 but I don't expect to do any better than this depth.
