Metal god, keep in mind that those reticules on your scope for bullet drop may or may not be correct for the velocity your rifle shoots that Federal ammo. There could easily be a 100 fps difference.

And they're only good for one elevation above sea level and one set of atmospheric conditions.

Changes from what they're calculated for could mean several MOA's of error at the longer ranges. There's a difference in a .308's bullet drop at 1000 yards going from 600 feet to 6000 feet elevation of about 5 MOA.
