Was looking at getting a new scope and am looking at the nightforce with reticle in 1st focal plane or a swarovski. I just found out that some scope manufactures have adustments in IPHY (inches per hundred yards) and not in true MOA adjustment, such as leupold. I would be using the scope for long range hunting. It seems like the IPHY would be difficult to use drop charts for and that a true minute of angle adjustment would be better. SO question 1 what do the nightforce and swarovski have? (IPHY or True MOA) Question 2 is there a difference, or is one better than another IPHY vs. True MOA ? Thanks for the help.
