Re: mil or moa
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: lostcoyote</div><div class="ubbcode-body">the math is RILLY EASY......
since there is 2*pi radians/circle = 6.2831853....
a 100 yard circle has the cicumfrance of 2*pi*100yards*36"/yard = 22619.4671088 inches.
====================
if we are going to use 1/4MOA clicks...
then there are 360 degrees/circle * 60 minutes/degree * 4 (1/4 moa clicks/minute) = 360*60*4=86400 1/4 moa clicks/circle.
and so 1/4 moa at 100 yards = 22619.4671088/86400 = 0.2617994 inches
(not quite 1/4 inch.... but we round it off anyways)
==================
if we are going to use 0.1mRad clicks...
then there are 2*pi radians/circle * 1000 mrad/radian * 10 (0.1 mrad clicks/mrad) = 2*pi*1000*10=62831.85308 0.1mrad clicks/circle.
and so 0.1 mrad at 100 yards = 22619.4671088/62831.85308 = 0.36 inches
=================
see how easy that is?

Not how I do it. I only remember 4 numbers:
1) 1 mil ~ 3.5 MOA
2) .5 mil ~ 2 MOA - 1 click (for 1/4 MOA turrets)
3) 1/4 mil ~ 1 MOA
4) 1/8th Mil or 1/10th mil ~ 2 clicks (for 1/4 MOA turrets)
Some one can just say some random number like you are 1.7 mils too low... well I just go up 3.5 (this is one mil), then go up another 2 MOA - 1 click (.5 mil), and go up another 1 MOA (about .25 mils).. I don't know what that adds up to, but I just semi-precisely made my adjustments
See no math involved!
