Looks good. Load up ten of the 2.015 COAL load and see how how it works at 200.

So far, are you happier with Varget and CCI primers?

Not sure yet. So far both look to shoot very well. Need to run Varget load over chronograph next week some time to see what I am getting. RL 15 and Fed 210 match primers appears to have possibly shot tighter groups. Might be about = with accuracy? So will see how it goes long range

Found the 44.2 to be optimal charge. Had a decent seating depth and some stuff happened and wasn't 100% sure where my seating depth was actually at so went back today and re-did seating depth test and found a better load than before. Since last load though I did uniform primer pockets and sort by neck wall thickness and switched to the Forster Ultra Micrometer Seater Die.
Here are the groups from today with diff seating depths. I used Bergers seating depth test method to work up. Started at 2.102" ogive (#1) and worked up to 2.227(#5) which is only 0.005 off the lands. #5 and #4 appear to be very promissing.

Shot at 100yds 75F and light winds(4-6mph) coming from 11 oclock

Cool beans. You've closed right in on it.

Switched to Lapua brass and Tula KVB7 primers. This is what I have going so far with only 4 rounds to develop the load. This is only 2nd time shooting 600 yards and only 3rd time ever shooting past 200 yards

Looks like the wind got you on the flyer since vertical is good with that shot.

Your vertical dispersion is good, less than MOA, so I'd call it good. Build a data book and start logging your shots to help you with future wind calls.
