Ridge Runner,
I get it! Thanks alot for the explanation once again. I am more of a hands on guy then anything else. So I need multiple examples on paper before it clicks!
I did have one question though, Just for future reference, how do you know that MOA is 1.4073" and not 1"? I was just curiouse because the top of the turret shows, " 1/4" at 100yards", so i assumed MOA would be 1". Are all scopes 1.4073 MOA or is it just the leupold VX2?

Thanks again,
Nick-

according to leupolds web sight they are all the same, inches per hundred yards and MOA, no difference, however my mark 4's say 1/4 MOA so thats what I use.
If your scope is IPHY then you just use .250 per click at 100, .5 per click at 200, 1" at 400, 1.25 at 500 and so on its still a degree thing.
It really makes no difference how you figure it till you get to extreme range.
say your scope is 1/4" adjustments and you figure .261 for MOA, and say you adjust 19 moa for a 1000 yard shot
your off .11" per click at 1000
19x4=76x.11" =8.36"

I see, wow.... I see why practice is so important. I went onto leupolds website so I new what to look for, for future reference and It says...... "¼-minute click adjustments for windage and elevation". So if Iam understanding this correctly it translates to MOA is 1" at 100 yards?

So if Iam shooting a .243 Win, I have a coyote ranged at 450 yards. Iam sighted in at 200 yards. My bullet has a 21.2" drop at 450 yards.

1 (MOA at 100yds) x 4.5 (translation of 450 yards) = 4.5
4.5 MOA at 450 yards
21.2 (Bullet drop at 450yds) / 4.5 (MOA at 450 yards) = 4.71 MOA

4.71 MOA translates too....... Adjust elevation turret UP 4MOA and 3 clicks. Which also translates to 19 "clicks".

Do I have this right?

Correct. The assumption was made we were talking about scope turrets with some sort with graduations marked on them. If you plan to dial your corrections on a regular basis this is something that will be at the top of your wanted list.

Ridge Runner's formulas and explanations work, he just missed that first shot by a couple inches. We've all done similar.

Short answer... yes. The real solution... get target turrets

We know that 1 actual MOA (vs a Leupy MOA) is 1.047" because there are 360 degrees in a circle and there are 60 minutes in a degree and if you do the math, 1 MOA @ 100 yds = 1.047" and @ 200 yds = 2.094" etc.
