If I zeroed a scope at 50 yards (load 120 gr bullet and 31.3 CFE 223), would the point of impact at 100 yards be higher or lower and by roughly how much?
Point of Impact - 50 to 100 yards

You need to know:
* Optic height above bore
* Projectile weight
* Muzzle velocity
* BC
* Temperature
* Barometric pressure
When I zero at 6600ft elevation, then come down to 4400ft, the POI shift is pretty big. I just did that this past week, and the zero stop would't let me go low enough to compensate for the low POI at 4400ft.
50yd zeros normally print high at 100yds though, with your scope height and mv being the biggest factors in how high.NRA Basic, Pistol, Rifle, Shotgun, RSO
