What if muzzle velocity was the same for all but still required different zeros for each person more in windage than elevation? A 1% to 2% spread in muzzle velocity won't cause a 1.5 MOA change in windage.Since different shooters produce different muzzle velocities with the same ammunition and rifle, it wouldn't be a stretch to assume that there would be different points of impact between shooters, no?
Funny, that's EXACTLY what happens when the .243 swaps between the bosslady and I, to my "zero" she will repeatedly put neat groups in perfect vertical alignment, but exactly 1.5 moa to the right. Doesn't matter if it's 100 or 500 yds, ALWAYS 1.5 MOA TO THE RIGHT. Why? I can't prove anything so maybe you could shed a little light on it? I figured her longer neck was the physiological reason.What if muzzle velocity was the same for all but still required different zeros for each person more in windage than elevation?

My son kept doing that to my .223's scope....I can tell you from people who insist on tweaking my sights so they can fire 12 rounds that it happens. Wish they would ask first, or not do it at all
