I have spent a lot of time this weekend and fired over 60 rounds working up a load for the 162 ELD-X in a 280AI. Thought I would share what I found on seating depth for anyone else trying to make them work.
I started at 30 thou off the lands and worked loads from 60 grains up with 4 shot groups. I thought I would get to 62.0 but at 61.6 the bolt got a bit stiff and I could see ejector marks so went no further. The best group was 0.8" (over 100 meters) at 60.8 grains so I decided to look at seating depths at this charge weight.
Working into 10 thou off the group grew to 1.1". At 50 thou it was 1.8" and then at 70 thou off it shrunk to 0.4". Moving on to 90 thou the group was 0.9" and then 1.4" at 110 thou.
I went back and checked the 70 thou group and got 0.5".
This has been the most fussy bullet for seating depth that I have ever worked up. Hopefully my experience with them can help someone else.
