Lots of good stuff here, thanks! I grabbed a range finder to begin this process, but it turned out to be a split image type intended for golf. Education takes many forms, LOL; I will try again....

I enjoyed your post, already had the milirads down from engineering calculations, but this is a practical use for ranging, thanks! The hummer was obviously not through a scope, but it does illustrate my question. Does the angle cause much distortion? Measuring front to back will give different results ( I know this is grossly distorted for a 500 yard scope hummer picture) but do you need to estimate center for best results?

Second question ( sorry, I know this is basic for you) with a laser range finder, does angle on the painted surface reduce the accuracy by bouncing the primary return off at an angle? I know it will reduce the needed return signal level.

As always you make me think!
