The lower you adjust your range the more MOA clicks I have to change to be zeroed in!!!!???? WTF can some body fill me in PLEASE!!!!!!!????? :( that's not wright is it??
Ok, first of all, this post is in the wrong forum to get a dedicated answer... I would recommend posting this in the optics forum. But to somewhat answer your question... MOA is a static number, MOA does not change as it is a degree of angle measurement. Just think of it this way, the degree of the angle measurement at the base of a triangle is the same as the measurement at the actual opposite point from that side. But the amount of MOA adjustment required to compensate will increase with shorter distances (even though the actual compensation is less...). Also, your scope is a second focal plane, so your reticle size will change with power ring changes..., but this will/should not affect "dialed-in" changes if you're using the main crosshair and not BDC hash marks.
