Milsurp Sights - Theory and Practice

[DP68]

Posting this as I think some may find it an interesting video on milsurp sights / adjustments from the Anvil crew. Starting at about the 3:50 mark is a very interesting and clever (IMO) take on calculating sight adjustment.

A couple of disclaimers as my intention is not to start a flame war about the veracity of video, I am neither promoting or voguing for the technical accuracy or mathematical correctness of this video

Pretty good video. The example and graphics of calculating sight movement was unnecessarily complicated and not clear or complete. It is much simpler using a ratio and not calling it a constant. The triangles should be overlayed so it is clear the angles match.

If you can’t recall how to derive the equation, it is

Sight adjustment = (sight radius)*(impact distance from Point of aim)/36/(distance from target)

Sight adjustment, sight distance and sight radius are in inches and distance from target is in yards. 36 is the conversion of yards to inches.

I think you mean

Sight adjustment = (sight radius)*(impact distance from Point of aim)/(36*(distance from target))
