Rifle Scopes MRADS

Not sure what you're asking??? MRAD and MOA are both angular measurements, try to stay away from linear measurement comparisons, for example it is a misnomer to think that MRAD = cm and MOA = inches, you're just asking for a world of hurt in doing so. That being said, 1 MRAD translates to 36" at 1000 yards, 18" at 500 yards, 3.6" at 100 yards, because MRAD reticles and turrets are typically divided by 10, so you have .1, .2, .3 etc. which means .1 (point one) mrad at 1000 yards = 3.6", 500 y = 1.8" and 100 y = .36". MOA has similar divisions, at 1000 yards 1 MOA translates to 10.47", at 100 yards it is 1.047" which many round to say 1" at 100 yards, but this is wrong and can lead to misses in long range shooting if you go by "inches" instead of actual MOA values. Both MRAD and MOA are just as accurate, they are just different units of measure but don't confuse them with linear units of measure. Personally, you should stick with MRAD and learn the system.
 
Isn't there a conversion formula in your scope manual?
Not inclined to get into a discussion about the benefits of MRAD over MOA.

Why did you purchase a scope with MRAD reticle, if you prefer the other?

Did you actually sight the reticle before buying, or was it bought online?
 
Use the chart on the left... or just embrace mil and go with it

Two things:
  • Is your scope the Viper HST, in second focal plane? If so, all of the following applies only when the scope is dialed to maximum magnification. If this terminology is unfamiliar, you need to read up on differences in first focal plane (FFP) and second focal plane (SFP). Don't ask which is "better." They're different approaches intended for different applications.

  • As described in earlier posts, mils and MOA are both units of angular measurements. If you are trying to figure out how many inches - a linear measurement - are in a mil or MOA, you are using the scope incorrectly. Like trying to use a ruler (instead of a protractor) measure the number of degrees in an angle.

    Learn to use the subtensions in your scope to correct your shots. For example, let's say you shoot at a paper bullseye at 200 yards. Your shot misses by some amount low and some amount to the right. Do Not think of the correction in inches - think of it in mils (or MOA) by putting your crosshair on the bullet hole, and, using your reticle's subtensions to see how many fractions of a mil of "up" and how many fractions of a mil "left" are needed. You Do Not correct in inches. You correct in mils or MOA.

  • I learned to shoot with MOA scopes over half a century ago and held onto MOA for almost two years of PRS competition. Then I switched to mils - not because "competitors use mils" but because it is objectively faster to dial mils mid- to high-end optics. You do not state how you use this scope - hunting, plinking, whatever. If you don't need to make fast adjustments under time pressure, mils vs. MOA doesn't really matter. Bottom line, with mils or MOA, is simple: Stop trying to think of shot correction in inches and learn to think of correction in fractions of a mil (your scope probably has 1/10 mil clicks).

Have a Vortex Viper 4X16X44 calibrated in mrads. Is there a SIMPLE rule for inch conversion? Can this scope be converted to moa?
Many, thanks

Question 1, forget inches. There is no need for inches.

Question 2, no it's in mils. Run data in mils and dial on or hold it. Done.
 
Thanks @Rob01

From my own experience it was an abstract concept right up until I started actively practicing it; then it was so intuitive like a huge light bulb coming on.

Guys just need to take the leap and shut off the “inches translator” and just start doing it even on their 100 yd range and it’ll be obvious.

No practical accuracy difference between moa and mils.

Also clicks should be forgotten like inches. It doesn’t matter how many inches something is at any range as the scope does not adjust in inches.

Never be reasonable.. I love adding and diving by 4, then rounding to the nearest 1/4th. Screw just moving the decimal point, what is the challenge in that?

Read this first. Should help you make some sense of the differences of why people are saying what they are.
