- consistent
Consistent — shot dispersion within each string dominates. Group centers land close together.
Hit probability Collective @ 100yd · 6 shots · MR 0.252″
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.
