Or in a combination of vertical and horizontal axis? And, if that is the case, why are we ignoring the horizontal dispersion in ladder and OCW type load development?

.1 grain increments are too fine. Generally for .308 size cases .3 grains is good. For magnum cases .5 grains

When you find consecutive shots that have nearly the same POI, you then shoot those individual loads to test. Pick the best and make seating depth adjustments if needed
