Re: 3-18x42 35mm FFP Sniper's Hide Edition GEN 4
Something I recently learned is that if you split the thickness of any of the lines it is .05 milrad....a tiny measurement which allows you to range small objects accurately or ...distant and small objects, something I never knew and came across by accident. I learned that in this post by Jon Boyette on another forum. I don't think he will mind me putting it here. He explains it better than I could. Sorry John........First the reticle w/measurements....
Again..the words below are John Boyette's not mine.
The reticle in the IOR 3-18x42 FFP is 100% based on .1 MILRAD in measurement. For ranging this is a critical step. To accurately measure and engage an object past 700yds with the standard calibers most sniper teams deploy with “5.56mm, 7.62mm” you would need to get to the .05 MILRAD reading. By doing this with the A5 “now the modified MP-8” reticle all you must do is split the thickness of any of the lines to gain the .05 MILRAD reading in the reticle as a whole.
Here is a simple chart to show you the difference in getting the .05 and not.
As you can see, as the distance grows the .05 MILRAD reading helps. Look at the last target size of 36”. With a 1.7 MILRAD reading you would range the target at 588yds. With a 1.8 MILRAD reading you would range the target as 555yds. That’s a difference of 33yds. Keep in mind, we are within intermediate target engagement range for 7.62mm SWS and at the upper end of a 5.56mm SWS engagement range. Will that 33yds cause you to have a miss? It might. Run the numbers yourself and see the difference the .05 MILRAD reading makes. The main adjustment is small targets at longer ranges such as this chart.
If you can read the .05 MILRAD reading you can now get a much closer ranging of the target to its true distance from you.
Using the reticle for holds:
You have a total of 15 MILRAD elevation an 5 MILRAD per side for windage. Holds are just as accurate as dialing when done correctly. IF you must engage multiple targets, movers, shifting wind and the like holding off is the best way to go due to the speed and accuracy gained by doing so. This reticle helps in such situations due to the ease of use of its design.
Optic Adjustment
The optic adjusts in .1 MILRAD. This is the best way to run any riflescope with a MILRAD based reticle. Why you ask? Well if you have to hold 1.3 MILRAD for a 300yd shot, you can also dial 1.3 MILRAD and engage that same distance. You o not have to flip/flop to a MOA dial. That same shot with a Leupold 3.5-10 MK4 with MOA adjustment and a MILRAD reticle would read like this:
4.50 MOA dialed or 1.3 MILRAD hold two units of measure MOA / MIL for no good reason
With the IOR 3-18x42mm FFP would read like this:
1.3 MILRAD dialed or 1.3 MILRAD hold
I see no comparison to a MIL/MIL optic over a MOA/MIL optic. It’s just a better system. To take this sideways, a MOA/MOA system is hands down better than a MOA/MIL system.
The adjustment of .1 MILRAD is at 100yds .36inches of measurement. So for three clicks you are at 1.08 inches. I like this just on the fact that 3 clicks = 4 clicks on a ¼ MOA scope less adjustment. Now, let say you are shooting at 600yds and you see your shot is .9 MIL high and .8 MIL right. Well you can hold off for the 2nd shot like any other riflescope OR like any other rifle scope in a MIL/MIL setup, just dial down 9 clicks, and 8 clicks left.
So basically you adjust to what you see. Try that with a MOA/MIL setup like a Leupold. To make my point this would be your adjustment.
.9 Mil high = 3.0 MOA down
.8 MIL right 2.75 MOA left
Unless you have a calculator or a mil-dot master right at your side you have to convert your adjustment from MIL in the reticle “the splash you see” to MOA to adjust. This kills time and allows the wind to shift more so than a faster follow up shot.
The elevation knob has 10 MILRAD in one turn. This is more than enough elevation in one turns to get you from a 100yd ZERO to 1000yds with most 7.62mm SWS. If you go with a MK-13 type system, you can get well past 1000ys in one turn. If you want to run this on a MK12 style system you will spend the life of the rifle in less than one turn of the elevation knob.
The merit of the MIL/MIL system is well known, I have just touched the surface of how it aids the shooter. This is a lesson the U.S. Army and Marine Corp are learning now. You will also see the Marines have dropped the MOA/MIL optics, and some units in the U.S. Army have also.
The ability to use the First Focal Plane “FFP” reticle is also a step up from a Second focal Plane optic “SFP”. If you are a shooter that shoots on a static range, no movers, no dynamic target engagement than a SFP optic like the Leupold 4.5-14 or 3.5-10 is fine. BUT if you shoot movers, pop-up ranges, unknown distance, practice mechanical offset, danger space and the like a FFP is not needed. But it will take out half of your misses down range and not let you make mistakes.
