Yeah increase rate of dispersal can decrease with distance/stability but rate of dispersal can not, if your rifle shoots statistically significant 1moa groups at 100 meters, it cannot mechanically shoot statistically significant smaller (angular) groups past that. Mental or shooter factors taken out of the equation. Including selection bias....... which is the most likely answer for the "my rifle shoots smaller groups at long range than close range" experience
and re: zeroing at 100m - I wasn't meaning a 100m zero per se, just shooting for zero at that range. If you actually have point of impact in the right place, whether it be right on for a 100m zero or 4cm high for a 200m zero, or whatever, it is an adequate distance to do it. Of course any error is magnified at range but 100m is far enough that any error should be very negligible, your point of impact should be zeroed to within half of one click of desired location
e: TL;DR version: The bullet will not curve back towards the target regardless of how stable it is.
