I wish you could explain this better.

1 meter = 39.3700787 inches and 1 yard has 36 inches how is this exactly the same at 1,000 yards? I would think that 1 meter would be 3.3700787 inches longer.

I would also think that 3.3700787 inches could cause a miss at 1,000 yds. if you were taking a head shot or keeping you out of the "X" ring and possible outside the 10 ring.

Please correct me if I am incorrect.

Thanks,

Re: Which route to take?

A lifetime in the military gives me a little different point of view....

Let me re-hash it a bit:

MOA is just a subdivision of mils, just like mils is a subdivision of degrees....

The whole thing is based on 6.283 radians or 21,600 minutes in 360 degs.... So 1 deg = 17.777 mils = 3.483 MOA

NATO and the US Military uses 6400 mils per 360 deg (just rounded up a bit).

The old Soviet system used 6000 mils, and the Swedish use to use 6300 mils, but I think they changed.

You can choose which way you want to figure distance but if you are using a mil dot scope with moa adj then???

Read my post agian. At no point were yard mesurements compared to meter measurements. One mil is the portion of the circumference of a circle that is exactly 1/1000 of the radius of the circle. So when you see an object which subtends one mil in a scope you know that's it's 1000 times the distance of the linear dimension of that object. It makes no difference what units are used, so it works for meters, yards, cubits, or spans. You must use the same units for distance and target size, or include a conversion factor. People who think metric units find that easy. If you think in yards and decimal yards it's just as easy. If you think in yards of distance and inches of target size you'll have trouble in either the mil or MOA. However one mil at 1000 yards is exactly 36 inches. One MOA at 1000 yards is an irrational number of approximately 10.47" You'll never make things easy by mixing metric and english units.

The mils on a Horus scope are the same mils used in a mil dot scope. The Horus reticle instead of just haveing two lines each 10 mils long fills in a grid over the entire usable shooting space. Therefore you don't move the reticle with respect to the rifle to aim. You simply move the target to the correct drop and windage of the reticles markings. You determine what the drop and windage need to be by the same method you'd determine how many mils you'd need to click the reticle on a mil-dot scope. But it's a lot quicker (and typically less error prone) then keeping track of clicks or reading scope turrets.

I went looking and found this and this guy does a grea job of comparing/explaining:
