Rifle scopes MOA vs MIL
Posted on 12/30/20 at 10:30 am

I see a lot of shooters on YouTube recommending MILs. Why is that exactly since we don't use the metric system here?

All of mine are MIL or MRAD.
It’s basically what you are used to.

The mil is not a metric-only thing. It's just a different way to break up angular measurements.
What it all comes down to with mils is that an angle of 1 milliradian moves the impact point 1/1000 of the distance you're shooting at and most mil scope turrets are calibrated to move the scope 0.1 mil per click. So, every time you click a turret, it moves the POI 1/10000 of your distance to target. So, if you've ranged your shot and you're shooting at 200 yards, you know that you are 7200 inches from your target. Since each click on your scope will move your POI 1/10000, each click will shift your POI by 0.72 inches. Once you know range to target, all you have to do is shift the decimal place 5 positions to the left to figure out how much each click moves POI when zeroing or dialing in holdover and windage.
It's just a different way of dividing up the angles. Instead of using 1 minute and having to remember that 1 minute is 1.047 inches at 100 yards and using that ant the range calculating back and forth to figure out how much that 1/4 MOA click (typical MOA scope adjustment is 1/4 MOA per click) is going to move POI, you can use 0.1 milliradian per click and just have to figure range and then move a decimal point to find POI shift per click.
It's moot, though, when you're using your scope to zero. You literally just look through the scope and directly count the adjustment you need directly from using the reticle to count the MOA or mils that you missed by. The value of mils becomes apparent when you need to dial in a scope adjustment on the fly. It can be much quicker and more intuitive to use mils once you become familiar with it because all you need to do is move that decimal place from your ranging.
Either way, they both work and what works for you works for you.

Mils is not metric. It works for any unit of length.
target size in meters x 1000 / measure in mils = range in meters
target size in CM x 10 / measure in mils = range in meters
target size in yards x 1000 / measure in mils = range in yards
target size in inches x 27.78 / measure in mils = range in yards
target size in meters x 1000 / measure in mils = range in meters
target size in CM x 10 / measure in mils = range in meters
target size in yards x 1000 / measure in mils = range in yards
target size in inches x 27.78 / measure in mils = range in yards

I think I understand. Lol..... I guess you really need to be hands on to really grasp it.

After all that, I still use MOA. I typically shoot 200 yards and in, so knowing that 4 clicks (on my scope) moves POI roughly 1 inch for every 100 yards is good enough for my needs and abilities.
If I were looking for true precision and were shooting out beyond 3-400 yards, I'd probably opt for a mil-based scope (and one with finer turret clicks than 0.1 mil) because "roughly 1 inch for every 100 yards" doesn't cut it anymore when you start talking about large distances.

Whichever you choose, make sure the reticle matches the adjustments. It will eliminate most of the math. Mix and match mil reticles with moa adjustments and the opposite is just an inconvenience and not necessary with the all the scope options available today.

All of mine are MOA. It’s like the other poster said, “it’s what you’re used to”.

And fwiw, I find mils much easier to work with when shooting long range. For example, my adjustment at 500 is like 2.5 mils. This would be something like 8.5 moa.
Its easier for me to just dial 2.5 rather than 8.5. Its not a huge deal, but its less numbers to mess up especially further out. Say 1000 yards, I'm at just under 8 mils and the moa equivalent is like 27.5 moa.

Unless you are shooting past 500 yards or so, or just want to dial in corrections, it really makes no diff.
Sight in at 200 yards, for almost every cartridge you will be 2 inches high at 100 and about 6 inches low at 300 yards, give or take an inch here or there.
A decent bdc will be all you need, just practice with it.
But, if you want to dial or are looking for long range capability, I personally like mils over moa.

My scope is MOA
ZERO FOR 200
-2 for 300
-5 for 400
-8 for 500
Give or take.
Pic isn’t great deer was 700 yds took pic through scope trying to hold my phone.
