Suggested re-zero
Group centre is 0.74″ (0.74 MOA) from the point of aim.
Elevation, dial UP
0.19 mil
0.69 MOA · 0.69″
Windage, dial RIGHT
0.07 mil
0.26 MOA · 0.26″
This is your zero, separate from precision: group size and mean radius don't change with it.

- Between drift
- 0.397″

- mixed
Mixed — within-string dispersion and between-string drift contribute similarly. Both dispersion and drift are worth investigating.
Hit probability Collective @ 100yd · 20 shots · MR 0.602″
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
Testing the Nomad L w/ Recoil X 95% certain this is a dead barrel (certainly very nearly there if not fully dead) - also nearly certain that the scope elevation turret slipped.
