[QUOTE="MontanaRifleman, post: 340731, member: 11717"] 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. Mark [/QUOTE]
