Re: Need some help (Mark4 4x14) TMR Reticle
I have the same scope and have been using it for a number of years. Since Leupold has taken a long time to offer matching turrets and reticles until fairly recently, we had to use both MOA and MIL. Kind of a pain, but useable. For your turrets, just use MOA data for your come ups.
.25 (1/4 MOA) clicks and .1 MIL clicks are different units of measurement. .1 MIL is about .36 MOA.
Anyway, what has helped me is to use JBM ballistics
http://www.jbmballistics.com/cgi-bin/jbmtraj-5.1.cgi Learn to use their data for your range card. What is really good about JBM is you can calculate both MILS and MOA in separate columns on the range card. You use the MOA data for your turret come ups and you can use the MIL information to use for your TMR reticle holdovers.
It's much more convenient to have matching reticle/turrets, but It is very doable on your scope.
There is a great chart that "AR15 barrels" made up showing the inch click values of both .25 MOA and .1 MIL out to 1000 yards. I'm not too computer literate and can't post it from my desk top, but maybe someone on the forum can post it.
If you want to know what a .25" click at different yardages comes out to, a useable way to calculate it is to think of the clicks as fractions in 100 yd. increments using the first number of you yardage for your upper fractional number and number "4" being your lower number. <span style="font-weight: bold">True MOA calculations are a hair more than this example, but gets you very close to each click value in inches at different yardages</span>
Example:
1/4 = 1/4" (100 yards)
2/4 = 1/2"
3/4 = 3/4"
4/4 =1"
5/4 = 1=1/4" (500 yards)
6/4 = 1-1/2"
7/4 = 1-3/4"
8/4 = 2"
9/4 = 2-1/4"
10/4 = 2-1/2" (1000 yards)
I hope this makes sense.
I still use my Leupold MOA/MIL scope, but I have bought a couple of new scopes that are MIL/MIL.
Maybe others cam chime in.
