Why chose .1 milliradian scope over 1/4 MOA

This question is for guys that have chosen an mrad scope over a MOA.


Just wondering why some people choose to work with mrad for a paper target situation at known ranges.

I see the obvious application when using a mil dot reticle to range targets at unknown distances and make corrections but if your just shooting at the range at paper why bother?


just curious...
 
I think that the most obvious reason would be to match the retical - mil retical =mill adjustments , Moa retical =Moa adjustments ..

Moa is slightly finer adjustment and is a better choice for longer range paper punching for score
 
.1 mill @ 1000m= 10cm of change in poi
1/4 moa @ 1000m=6.98cm of change in poi
There hardly a difference its just personal preference

Just to be 100%sure .1mill is 1cm @ 100m right?
 
Most aren't buying them for shooting at known distances. Its just that the vast majority of ranges here where people can go out to practice are known distance.
 
Mostly because some shooters think it's cool to say they have a mil dot reticle. Mind you, fine adjustments can be handy.
A mil, not a mill, equals .001" or .0254mm. It's also a unit of measure equaling 1/6400 of a circle for the arty guys.
You have MOA adjustment because the U.S. doesn't use anything metric except their money. Their military uses metric though. However, scopes are primarily made for the civilian market. The military doesn't buy stuff from Cabela's.
 
a mil-radian is not metric or imperial it and unit of angular measurement.

it's more course than moa.

the only thing about it that might have a slight edge on moa is it works well with metric based units of measurement.

the thing to take in to consideration with a scope is matching the reticule to the turrets.
 
as far as why I have purchased a mil based scope with mil hash mark reticule is for rapid hold overs and windage adjustment.
 
A mil (in this case) refers to the equivalent of about 3.6"@100 yds. and 7.2"@200 yds and so on.
A MOA (in this case) equals 1.047" @100yds and so on.

A mil/mil scope is generally a .1mil click or about .36" per click.
A moa/moa is generally a 1/4 MOA click or about .26" per click

The math is easier if both reticle and turret knob match, regardless of which type is used.
As mentioned, the mil/mil scope is a coarser(less fine adjustment) relative to the moa/moa setup

There are however scope setups with 1/8" per click and also various combinations. I still shoot a mil/moa scope and simply divide the miss in inches by the yards/100 to get my moa comeup.

It's in reality more simple than it can be explained in writing. Almost everyone gets lost sometimes in all the trigonometry and specifics when attempting to make sense of milradians and minutes of angle.
 
Targets are sized in MOA globally so target shooters will use MOA as their adjustment value of choice.

It is THE convention when chatting with LR shooters that aren't in uniform.

The "MRAD" system is simply a base 10 version of the Mildot from post WWII. Todays reticle trade dots for lines which are vastly easier to measure with. They are exactly the same thing.. and an angular measurement. It is not Metric per se.

As long as the reticle and click use the same value, there is no benefit to either for field shooting. Just make sure your rangefinder and ballistics info use the same units as the scope... been there, been confused :)

If you are target shooting and the clicks do not match the target, it is a pain to try and center the group. At 1000yds, we demand 1/8 MIN clicks (1/10 would be even better) because it becomes increasingly difficult to use the scope to center a group when click values increase in value.

When a shooter decides on the style of shooting, the parts get really easy.

I went with Mil/Mil, FFP, zero stop scope because it seems the most straight forward and easiest to use/understand. I can look at the impact and make a quick, easy, straight forward adjustment to my POA or adjust the turrets. To me it just makes logical sense and reminds me of the old KISS method, "keep it simple stupid".

I know if my shooting is bad it's because MY shooting is bad not because I got lost in my scope, turrets, or conversions.
 
I have stayed with MOA/MOA on my target scopes because that is what I have on my hunting scopes. IT keeps everything simple for me..... and I like simple ... especially with so many other complicated variables ... especially after going through Bryan Litz's long range shooting materials :eek:(
However I didnt actually realize that MOA provided finer adjustments until I read this thread so that suits me fine
 
At first, I was going for mil scope but changed my mind and went for MOA/MOA scope which is excellent for F-Class. Also for me, it is easy to use MOA if you were taught in inches. 1/4", 1/2", 3/4', 1 inch. 1/4" per click at 100 yards.
 
For the most part American snipers have all gone metric as well. Its just easier to compute the firing solution IMO. Also keep in mind that most manufacturers make a .05 Mil adjustment for their products now. And here is the biggest reason...we live in Canada which=Metric.
 
1 MOA = 1/60th of 1 degree of angle
1 MOA = 1 nautical mile on the earths surface
1 nautical mile = 1.1508 miles
60 minutes x 360 degrees =21,600 nautical miles x 1.1508 = 24,857 miles which is roughly the circumference of the earth

Its not metric or Imperial its a measurement of angle.

Great story bro.
To anyone in the shooting world that matters...MOA is imperial and Mils is metric. 360 Degrees in a circle=imperial. 6400 mils in a circle=metric
 
There are 360 degrees in a circle no matter whether you're in metric or imperial - degrees as a unit are used in both systems as the angular unit of measurement.
MOA just further subdivides a degree into minutes (1/60) and seconds (1/3600), while mil is based on 1/1000 radians (2pi radians in a circle).

Hang on... do riflescope mils use the 'true' measurement for a milliradian (1/6283.185...) or the artillery value (1/6400)? As far as I know, for accurate stadiametric rangefinding, you MUST use the trigonometrically accurate value of 1/6283.185..., no?

*edit, I guess using a different value just puts a different conversion factor into your rangefinding equation. Still, using the trigonometric value would be simpler, since you don't need to take an angular value into account at all, it's just a straight (base 10) ratio, yes?
