Given the same type and weight of the round of ammo being fired, the graph looks GTG. But what about 55 vs 62 vs 75 grain shot with the same zero? It appears in my mind, there may be some variance in trajectory based on velocity, bullet weight and powder charge. I've zeroed at 50 and 100 yards, using different bullet weights, checking accuracy and shot groups, between different ammo manufacturers. I've always had to fine tune my zero to get the same POA/POI as I switched from one bullet weight to the others.
