MontanaRifleman,

So if I understand correctly 1 MOA at 100 yards = 1.407" on all scopes. Not just leupold scopes? Iam starting to see the full picture now.

Iam really starting to get into this stuff!

Iam about to purchase a leupold VXII 4.5-14x40 because the rifle iam going to mount it too will be a "all around hunting rifle, but I would like the capability of shooting long range with it. (Kimber Montana 300 WM). I have noticed not many people have leupold scopes on their rifles or atleast this particular model. is there a reason for that? Should I consider a different scope?

Thanks,
nick-

Nothing wrong with Leupolds, I own em and don't think you'd be disappointed with one. Not wanting to get into a contest about what determines LR but for me anything 800+ yards is getting there and so if your talking in the same ballpark then you might want to consider something with a little higher magnification...well at least for me it's the eyes are getting older. You may also want to consider a NF-very rugged 5.5x22 but pricey.

Nikolakangrga,
You have one mistake in your past comment:

1 actual MOA is 1.047 not 1.407.
As explained by MontanaRifleman

 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.
It is important that you have the numbers right for this.
Hope this helps.

Nick,

I have no personal experience with Leupold, but from other posts I read, it sounds to me that they do NOT use a true MOA turret. Many scope manufacturers use IPHY (inches per hundred yards) and call it MOA because it is close.... 1" vs 1.047". It doesn't really matter as long as you know what you are using and compensate for it accordingly. But there is a difference and at extended ranges it will add up. The difference @ 1000 yds for 1 MOA of travel is about 1/2", for 10 MOA it's about 5" and for 20 MOA it's about 10", which is a typical drop for a lot of cartridges.

I prefer the true MOA because that's what most ballisitc programs use and there is no confusion in terminology. The IPHY system is less mental work if you think in inches.
