front sight height question

varian

on a rifle is moving the height of the front sight by a given amount the same as moving the height of the rear sight by the same amount. is it a one for one ratio

Yes, but in the opposite sense.
A taller front will lower the point of impact.

vsrisn,

Exactly, they are opposite of one another.

Here are a couple of methods to use for the calculation:

Best.

Think "Front sight follows the bullet impact" - so if bullet impacts higher than point of aim (POA) raise the front sight (or if bullets impacts lower than POA lower the front sight).

Exactly, how much raising/lowering dy can be determined by

dy/(rear to front sight separation) = dx(impact relative to POI separation)/(range distance)

thanks all. i have the direction thing down, i was just wondering about if it is a 1:1 ratio. thanks again.
