i am getting a new sightron 6-24x50 lrmoa WOOHOO! i would like to know what my 12x and 18x moa strata value is. if at 6x the space between two strata is 8.0 moa and at 24x that space is 2.0 moa what is (?) 6x=8moa, 12x=(?)moa, 18x=(?)moa, 24x=2moa thanks guy's

You are correct in that 6X would be 8 moa.

12X will be 1/2 the subtension (strata) so therefore 12X = 4 moa.

That being said, it would stand to reason that 18X is 3 moa, but it doesn't quite work out that way. 18X will actually equal 2.7 moa. 16X will equal 3 moa.

Here's the equations:

24/12=2X
2x2moa=4moa

24/16=1.5X
1.5x2moa=3moa

24/6=4X
4x2moa=8moa

If you want your spacing to be similar or very close to mils, then reverse calculate and you come up with 13.96X to get 3.44 moa spacing. 14X will be really close.

24/13.96=1.719X
1.719x2=3.438 moa or 1 mil

Test this on a yardstick at exactly 100 yds to verify the power changes are exactly as advertised. Some scopes that say 24X are actually only 23.5X type of thing.

Hey that's great. Glad to hear you like it so far. Mine just came in too, but I haven't actually laid my hands on it yet.

I've never owned a Sightron before, but I thought I'd give it a try after reading some threads on this site. Been buying Nightforce for a long time because of the MOA reticle.

Price wasn't as high as I thought it would be either, just under 9 bills.

Glad to learn these Sightron SIII LRMOA scopes are now available. Been waiting for these since I learned of their impending release.

They might still be hard to get, at least it was through my local dealer. He said he could only find two. I never checked Midway or any big outfits though.
Hopefully I'll have it in my hands along with a new (new to me) 243AI by the end of the week, first of next week.

If you are looking, these guys have some Long Range Accessories

I also have one of these and they are top notch, love the reticle, nice and thin and the nobs are big with positive clicks. Get one you will not be disappointed.
