This is a good explanation of MOA and It should be a good explanation for some.

Sorry, Some how this video ended up in the wrong place will look for the correct one.

x2, i watched this video when it first came out in 2011 when i started getting serious about long range shooting. i had read books about long range shooting and it never clicked for me until i watched this video.

I like R. Cleckner, I have his book and recommend it often.

However, in this video (as in his book), he again perpetuates the worst way of thinking of Moa as it pertains to scope adjustment.

In this video, the thought process goes like this:

I am (x) number of inches low...(x) number of inches is (y) number of Moa at this range, because (x)/(y)= my adjustment in Moa.

Isn't it easier to say:

"I have an Moa ruler 6 inches in front of my face. My Moa ruler showed me that I am 2 Moa low. Therefore, all I need to do is either hold or dial 2 Moa."

Moa and Mils can, and should be used in exactly the same simple manner.

All this converting and math came about when we had nothing but simple duplex reticles and had no choice. It doesn't have to be this hard.

of course that's easier once you've made an initial shot. but if you want to dial prior to the shot and you know your rounds ballistics, he's explaining it so you can use your scope. too many times i've had people ask me "how many clicks do i need to go up?". they sit there and try to figure out what a click is at each range and then just confuse themselves. this is good way to think about it (in my opinion of course).

Of course. It is only after you've shot that you need the correction. That is when these principles are applied, and as quickly as possible. The wind doesn't stand still and neither do animals.

If you are dealing with a shooter that, according to their dope chart needs say...20 moa for their first shot, and can't read a turret, can't read a reticle, or at least multiply by 4 to get the number of clicks...then what Ryan was talking about went way, way over their head to begin with.

A certain elementary level of mathematical understanding is certainly required for this hobby. Some just aren't going to get it.

Here is another option if using a duplex reticle or a traditional non-dialing hunting scope:

Multiply wind (in mph) x yards (to the nearest hundred) then divide by 3.

Example: 5mph x 4 (hundred yards)= 20. So, 20/3= 6.6 inches.

Since you should know the general size of the animal or the vital area, you use the animal itself for reference.

This only works within 500 yards, and isn't exact. But it will work plenty well for most.

If you are shooting a superduper magnum, you may use 4 as your divisor rather than 3. You just gotta see which works best for your load.
