Hiders, so as I’m working my way through this past few days testing I realized I overlooked something. On the group at 2.1 CBTO, 3 shots were dead nutz into one hole, whereas I had looked towards 2.118 CBTO(jamming .1 into lands) as the best results.

I am debating on loading up some more CBTO tests from 2.118 to 2.10(broken into 5 groups of 6, shooting 2 3rd groups of each) and seeing what I can replicate/discover. Since this is my first foray into reloading .308 so all advice is welcomed. I’m wildy OCD so this has become all encompassing

I am not the greatest shot so my consistency is lacking which makes the testing tougher, but I'm working on it. The vertical dispersion on 2.118 was closest, but the 3 in one on 2.1 has me curious. I pulled the lone shot on the 2.118, not sure about the others as much
