I've plotted up the Horizontal POI spreads vs muzzle velocity. This confirms my suspicion that POI shifts right as MV increases.

I've plotted up the Horizontal POI spreads vs muzzle velocity. This confirms my suspicion that POI shifts right as MV increases.
But I now see that the 3.050 inch Cartridge Overall Length produced the smallest group in both horizontal and vertical spreads. I suspect because of neck tension on the bullet, or this bullet does better with more jump to the lands.
I'll add the plot to this thread when I get home.
