Mil-Mil Scope Tracking Target

[ShadowsEye]

Hey there, I recently purchased a Mil-Mil scope and wanted to be able to test how well it tracks, since a full Mil at 100 yards is 3.6 inches, I decided to make my own target for the test. nothing fancy, but I thought I'd share.

Cool.

i run a box test on the sight in type targets with a main bull and then 4 smaller bulls near the corners. one shot at a smaller bull (say top left). measure with the reticle your correction to get on the top right, fire a shot. measure to get on bottom right, fire shot. measure to bottom left (should be the same amount of correction you came right) fire shot. then measure back to the top left bull and fire last shot (should be the same amount of correction you came down, and you should hit the starting bull.

Yeah that's what I normally do too with 1/4 moa-adjustment scopes. It would work for testing the return to zero on a mil scope, but I wanted to test whether 10 clicks was truly a mil. (also wanted to keep 1" targets on a printable 8.5x11 sheet of paper as well.)

i take an ipsc cardboard target, a magic marker and a square and draw a long vertical line. every 3.6" i make a big X in the middle of the line. i prefer that to + as the hashes on my crosshairs cover up the +, but it's easy to see if all the lines that make up the X intersect in the middle of the +

Man Taliv. I never thought to do something like this to verify that the reticle is properly constructed.

I haven't taken my FFP IOR out in awhile, perhaps I should consider this exercise.

In fact, I haven't shot much of anything other than 22 long rifle in a very long while, other than my 243 coyote rifle.

yep, if you have a mil-dot reticle, you first use that to make sure your dots/hashes are where they're supposed to be. then you fix the rifle in a vice, and dial up and down to make sure your turrets track. AND to make sure they're level. i had a scope once that when i would start it out on the line and dial up 5 mils or so, it would be about 2 tenths off on windage

...dial up 5 mils or so, it would be about 2 tenths off on windage

How did you correct this? Was the problem in the reticle or the scope adjustment or just mounted out of plumb?

Thanks.

i shipped it back to the mfg.
(it wasn't doing it when i first bought it. i think i had 5000 rnds under it before i started getting extremely frustrated with my wind calls and finally box tested it)
