acss code cracked

This is probably not a revelation to many of you, but it was to me and hopefully it will save other some of the frustration that I have experienced.
I purchased a primary arms 1-6 x24 lpvo scope and absolutely love it. However they won't release the subtensions of their reticle. It may work perfectly but I just had to know the details, and I couldn't find the information anywhere. So I dowloaded strelok pro and finally reverse engineered the reticle. Here are my results, this is for the acss 5.56/.308 reticle:
300 yds 3moa .9mrad
400 yds 6moa 1.7mrad
500 yds 9.6 moa 2.8mrad
600 yds 14.2moa 4.1mrad
700 yds 19.1moa 5.6mrad
800 yds 25.3moa 7.4mrad

This may not be exact but it should be very close.

Thanks for your work. That's exactly the scope I have.

Yep, Primary Arms are silly about this. I had to do the same thing with my 6.5 Creedmoor running their Apollo 3-18x 6.5CM scope. They give calibrated drops out to 1000 yards, which is nice, but that's going to be particular to one ammo at one atmospheric condition and one muzzle velocity. Here is the scope on the 1400 yard gong-range on top of a PA 6.5 CM 20" (kind of a budget AR10 package, that's not so bad).



Here is the reticle with the drops, where they go from 300 yards out to 1000 yards (3-0), in the bottom vertical, using Hornady 143gr ELD 6.5CM (I think). And with that ammo, it's not bad, you can point and ping pretty close to on, out to 1000 yards:


But they won't tell you the distances between the drops, you're on your own if you use different ammo. So to figure them out, I pulled the above image, dropped it into RangeBuddy App,

and calibrated the distance using the upper vertical section, which is MIL's, and then measured the drops distances. So, for the Apollo 3-18 6.5 Scope:

yards Mils ( +/- 0.1 ; on Apollo 3-18 6.5CM)
300 = 1.0 Mil
350 = 1.4
400 = 1.8
450 = 2.2
500 = 2.7
550 = 3.1
600 = 3.6
650 = 4.1
700 = 4.7
750 = 5.2
800 = 5.8
850 = 6.4
900 = 7.0
950 = 7.7
1000 = 8.4

Top of post = 9.4

nice work. it's frustrating that it is needed though.
