Help with MOA!

[rockytopmojo]

I bought a Vortex Tactical scope last year. I wasn't paying attention and got the MOA. Anyone have any good resources to help me understand how to use it? I'm lost! I've watched YouTube videos, but none really explain how to make adjustments and such. The longest shot I would have on my lease is 300yrds.

Thanks!

MOA is not very much different in the inches you are used to. In other words a MINUTE OF ANGLE is equal to 1.0472 inches. Your scope ( I assume ) is .25 MOA at 100 yards, which is so close to ¼inch that it is irrelevant. Where it really comes into play is a distance. Say your at 400 yards, every click is going to move you 1.0472 inches.

What caliber gun are you shooting?

7mm mag

At 300 yards, 1 moa is essentially 3.14 inches. Close enough to say 3 inches. Not sure what your question or need help understanding tho

So this is with .300 win mag Hornady 180 grain ammo. Anything inside 200 yards I am just holding dead nuts. At 300 yards it has about 7 inches of drop. At 300 yards a 1/4 moa/inching will move the bullet about .75 inches so you would need to make about 7-8 clicks up to put you damn near dead on. Remember if you zero at 100 on a 1/4 moa scope and then rezero at 50 for whatever reason that 1/4 moa is now an 1/8 of moa scope because it is designed to shoot 1/4 moa at 100 and you are zeroing at half the distance.The opposite is true if you zero at 200. Each click instead of being 1/4 moa or inch is now 1/2 moa or inch and so on. So at 300 yards each click would be 3/4 moa or inch. Just think of minute of angle (moa) as an inch and the math is easier lol.

A minute of an angle is 1/60 of a degree.

The impact difference in inches of a one MOA adjustment at a distance of Y yards is Y*36*tan(1/60 degree).
* means times (multiply)

The 36 is because that's how many inches/yard if you are wondering

Basically at 300 yards just proceeded as normal. Not enough distance to matter. At 100 yards each click will move point of aim .25 inches and at 200 .5 inches etc.
