MOA vs MRAD Vortex Viper PST

Hey everyone,

I am looking at a putting a FFP 4-16 Viper PST on a future elk/moose hunting rig. My question is, is it easier to range with MOA or MRAD or is it all the same as long as the reticle and turret match? Any thoughts would be helpful. Thanks. FYI, all my scopes right now have adjustment in 1/4MOA clicks, but I don't have ranging reticles or anything like that.

    I just purchased one of these for my
    Elk and moose rifle. I choose the moa only cause I know it and it was easier for me to learn

    If you are programmed in inches and yards go MOA. If you can think in meters and centimeters go MILRAD. Both are much easier to use if you use the units of measure they are designed around. If you don't you will have some goofy math to do that usually requires the use of a calculator.

    Personally I have found 1 MOA hash marks to be easier and generally slightly more accurate than the typical 0.5 MIL hash marks in Mil scopes.

    The MOA proponents say it's more accurate using 1/4 MOA than .1 MRAD as its a smaller increment.

    The MRAD proponents say it's quicker to calculate in MILS compared to MOA or Shooter MOA.

    IMO it does not matter. Both are proven and dependable. Pick a system and stick with it. Ranging with a scope is rather difficult. Unless you know the size of the object, it's really a crap shoot on how accurate the measurement is. Even knowing the size is not easy. I use the training tool called the Shooter Ready simulator computer game that gives many different scenarios with different sized targets and you range them with the reticle. It takes practice as well as regular practice to get accurate.

    I went with MOA. I think MOA and while hunting I use a laser range finder.

    That's entirely incorrect, mils are not based around metric; rather, around 1/1000 of the radial distance, an angular measurement. That's why it's easier to range in mils for either yards or meters: You know a person is around 2 yards tall, so you take 2/mils measured*1000 and get the range in yards. Or, a person is about a meter from their crotch to head, so take 1/mils measured * 1000 and get the range in meters. Or whatever else the target size is, use that as a base--the target plate I have is 18 inches, exactly half a yard, so I use 0.5/mils measured * 1000 and viola, my range.

    Personally, I went with the mil/mil version and could not be happier, even though my prior scope was 1/4 MOA adjustments. Mils are easier to learn, IMO. I would never use MOA anymore, it's not exactly an inch; the only benefit I could go to is IPHY (inch per hundred yards). That's because it's easy for me to estimate in inches on the target...but why, I ask, when you can use the reticle to measure? I've never zeroed the scope as fast as I did this one. One shot, measure in the reticle, adjust and shoot a group. Tweak. That's all she wrote.

    Mil/mil is the way to go, IMO.

    I went with MOA and this will show you why:

    Mil/mil is the way to go, IMO.
    I would agree with simplistic, but entirely incorrect? Not exactly. 1.0 MIL is equivilant to 10cm at 100m. The 0.1mil clicks found on most mil based scopes is 1cm at 100m. Like you stated it is an angular measurment, the departure from it's start increases, just like MOA. So at 200m 1.0 MIL equals 20cm, 30cm at 300m etc. A 0.1mil click would be 1cm, 2cm, 3cm etc.

    I'm 5'11" tall so 71" or 180cm. If you were to range me using a MIL scope and come up with 3.0 MILS the formulas would be as follows:

    71" x 25.4 / 3.0mil = 601m

    180cm / 3.0 mil x 10 = 600m

    Using your 18" steel target

    18" x 25.4 / 3.0 = 152.4m

    46cm / 3.0 x 10 = 153.4m

    If you were using an MOA scope to come up with ranges in yards it would be:

    inches/size of object in MOA x 100

    Using a measurement of 12MOA with the above known object sizes:

    71/12 x 100 = 592 yards

    18/12 x 100 = 150 yards

    I can do the second formulas for MILS and the MOA to yards in my head or very quickly on a scratch pad, as they are just moving decimals around.

    From a simpltons point of view having used both systems, if you think in inches and yards I would go MOA if you think in centimeters and meters MILS may be your best bet.

    As far as scope adjustments you can do your same zeroing scenario with an MOA/MOA scope
