    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.

    I have a leupold and I use nightforce on a ppc If it says come up 15 MOA then I dial up 15 MOA if I do my part and judge the wind then I pull the trigger and hit the target so can you explain how leupold is not a true MOA ? Not wanting to argue just curious.

    There is a difference in MOA( 1.047"@100 yards) and IPHY (1"@100 yards) the error would be amplified the further away your target is if you calculate with one but your scope uses the other.

    As long as you know which your scope uses that I don't see what problems you could have. You can print drop charts either way.

    I used to count clicks befor I had joined this site now I only think in terms of MOA as I believe this is the best way.

    I called nightforce and swarovski and their reps told me that both are in true minute of angle adjustments, not IPHY.

    I also prefer MOA. If you use IPHY you don't have to count clicks anymore than MOA.

    Jmason,
    I used to count clicks say 22 clicks got me dead on at 400 yrds now I dial in MOA so how would it work in IPHY ?

    Thanks Bigbuck

    You would dial 5 Inches and 2 clicks instead of 5 MOA and 2 clicks for a scope with .25 MOA or IPHY clicks. There's no voodoo to it. In MOA your unit per 100 yards is 1.047" and your unit for IPHY is 1". That .047" difference only starts to matter as you get out there.

    Don't sweat it! What's far more relevant is checking exactly what your scope actually shifts in, right throughout the adjustment range you'll be working in, not just by going by what the manual states. A hell of a lot of scopes don't move what they say they do, consistently right across the range. Nightforce generally do, and leupy Mk4's are pretty good, but I check 'em all on a test grid at precisely 100 yards. Any good ballistic program allows you to input your exact adjustment value as well.
    As for counting clicks...that's a recipe for a balls up if ever there was one!

    A half inch per MOA. If your drop is 20 MOA @ 1000 yds, that's 10" dif... Just so there's no misunderstanding.:)

    You're quite right Montana, that was misleading. I've edited my post. 1/2 inch per MOA is correct - read twice, post once!

    I forgot to mention that IMO it's easier to communicate with your partner or spotter w/o confusion in MOA rather than IPHY.
