Jump dev shot group analysis

[OldNavyAlpha]

Hi all, just recently broke in my new 308 FTR rifle, ( thanks to the helpful comments on fixing tight loading) and during load dev i jammed 10 5 shot loads, 3 thousandth out to 30 thousandth. Lapua brass, Berger juggernauts 185, Varget powder 40gr and win primers. I see two great shot groups here but wanted to hear from the forum on my shot analysis and where to go from here, powder charge test?

tip down left to right in a z pattern. Starting with .003 off lands progressing to 30 off
