That 28.4 load looks really nice!
28.9 I don't always do a good job of closing the top of my 9's especially with a sharpie and light contact.
After the session that I posted, my suppressor was tight coming off and spun off the CK muzzle device so I had to reset it and added a bit of blue loctite. I also changed gas blocks to a Superlative and run it in the bleed off setting about 48 clicks out.
SD at 28.9 is a bit high for my liking. I was out again with 29, 29.1, 29.2, and 29.3 pushing up past max. It was uncomfortably cold out so my groups were so-so. The 29 gr charge had a much better SD and a decent group so that is what I am focusing on right now. I'm kind of torn between the 90 and 103, but leaning more towards the 90. I'll comment more in another post.
At recent session I found a pretty substantial POI shift (approx 4" down and right) that left me scratching my head. I think it mostly came from the muzzle device remount near as I can figure. It's indexed same/properly so not sure yet Velocities remained same/similar. I use a Bobro QD mount and at first I questioned it, but I followed up the session with a quick zero check of a thermal and found similar shift.
