Within-string MR: 0.428" (0.43 MOA) Between-string drift: 0.108" (0.11 MOA) Between / within: 0.25× consistent

Consistent — shot dispersion within each string dominates. Group centers land close together.

Hit probability matrix — 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.
