Re: I disagreeJohnny,
By my figure, When you re-zero at 100 yds. You will now have moved the 25 yd, impact point 3/4" to the right.
There is no way to zero a weapon w/side mtd. scope at more than one range.
All other ranges will be in error by the proportion of the crossing angle, which is Tangent Angle = Scope offset / range (distance)
Its got to be,
But as you suggest, If you zero at a very long distance the maximum error appears at the shortest range and is never more than the scope offset distance.
