perfect. thank you!

You bet!

I use a large reel tape measure and set a target at exactly 143ft 3in (47.75 yds) where 1 moa is exactly .5 inches. This lets me use yard stick as a target reference rather than an MOA scale.

I have not done the math to see where 1 mil equals 1 inch or 1/2 an inch, but that shouldn’t be too hard to run the numbers.

I do it similar, just at 100 yards. 10 mils (36' @ 100) or 34 MOA (35.6" @ 100) at a time, throughout the scope's adjustment travel. Check the scope before even mounting on rifle using a rail mounted on a block. Then if it checks out, re-check it on the rifle (shooting) to make sure things are lined up. Have sent scopes in for service before mounting, or do as dfanonymous stated, and insert a correction to the turrets adjustments into the ballistic app.

Somebody check my math on this:I have not done the math to see where 1 mil equals 1 inch or 1/2 an inch, but that shouldn’t be too hard to run the numbers.

A mil is 1/1000 of whatever you are measuring. So if 1000 inches equals 27.7777778 yards, then 1 mil is 1" @ that range.

The .7777778 yards equals 28.0000008"....

so 27 yards + 28" for all practical purposes

1mrad = 3.6" = 3.44 moa at 100 yards

a mil scope measures mrad.

Guess you have a point there, been a shooter for many years and nobody has ever brought that up. Guess the difference between military/shooter lingo and something like machine work could confuse someone. However I’ve never heard anyone adjust a scope or give a correction in mm (what I thought was the standard abbreviation for millimeter, not mil). Centimeters (cm) scope adjustments yes, but not mm. Even then, when I see a scope adjustment in cm I just know it’s mil (milliradian) and don’t give it another thought. The abbreviation for milliradian or “mils” is a “m” with a right hash mark through it, to distinguish it from meters (kinda hard to do on a phone).

We do however use mm in the characteristics of weapon systems, such as 7.62x51mm chamberings or 2 & 7mm peep sights. You say MRAD in some some circles and they will think a type of radar system. Guess in this case it’s assumed the person or audience would know the correct unit of measurement for the intended purpose.

But did you at least check my math?

a mil other places might be short for millimeter but a mil in the shooting community as far back in the military as i can remember has always been short for miliradian...which is also called mrad by some other people and manufactures. So as far as jargon is concerned...they are usually synonymous.

This has no real functionality though unless you are just trying to figure out the scope adjustments when bzoing at a closer range. so 1.00003ish inches.

27.78/1000

however this, is unnecessarily complicated. When talking about inches yes. in the formula when doing a range est with mils, the easy way is to round off 27.77 to 27.78. As to figure out what the mill angle is at that distance...the rounded number is going to be a fraction difference. .027. So + .03 mils difference by rounding the .7777778 to any form of 28"Somebody check my math on this:

Yep, and that's exactly what was happening. Wasn't using the mil-relation formula for range estimation on a distant target of known size, just finding the yardage where 1 Mil equals 1".a mil other places might be short for millimeter but a mil in the shooting community as far back in the military as i can remember has always been short for miliradian...which is also called mrad by some other people and manufactures.

Oldfortyfive,

We are on the same page with checking the scope prior to mounting it on a rifle. The "rail mounted on a block" I mentioned earlier is simply a picatinny rail screwed down to a block of wood that is affixed to a sturdy bench that is concreted into the ground. It takes a bit of time to get everything lined up but works great for checking turret adjustments and for reticle canting and movement in the scope. Unfortunately even when finding an error, the manufacturers will allow a certain amount of discrepancy.
