Suggested re-zero
Group centre is 0.22″ (0.22 MOA) from the point of aim.
Elevation, dial UP
0.06 mil
0.22 MOA · 0.22″
Windage, dial LEFT
0.01 mil
0.04 MOA · 0.04″
This is your zero, separate from precision: group size and mean radius don't change with it.

- consistent
Consistent — shot dispersion within each string dominates. Group centers land close together.
Hit probability Collective @ 100yd · 20 shots · MR 0.457″
Assumes shooter dispersion is the dominant error source and scales linearly with range. Doesn't model wind, MV SD, or BC uncertainty — those matter more as distance grows, so real-world hit rates at long range will typically be lower than shown.

Notes
There is an outlier towards the center that came from the .308 when I aimed at the wrong target like a genius - it is not part of this session of ammo/action, so is not counted.
