Heads up on leupold scopes (MOA vs IPHY)

So I recently purchased a leupold vx-3 scope. I did a lot of research on scopes I wanted MOA adjustments and a ballistic reticle. Had a vortex wanted a nightforce ended up with a vx-III 4.5-14 varmint reticle. They are advertised and listed on their website as MOA adjustment and even marked on the turret as 1 click = 1 min but guess what called their tecs with a question and found out they arent MOA but IPHY (inches per hundred yards) and he had no answer as to why they are advertising false information. So heads up if you are looking at leupold. Im thinking about going to Vortex PST as they have true MOA turrets (I actually called to check). I just dont get what leupold is think making such a false statement and knowing that its inaccurate.

I have never heard this before... Not saying the guy didnt say it, but if that were the case I think one of us would have figured that out by now. Maybe I am uninformed and its common knowledge.. Hopefully more people chime in on this. but my leupolds match up with moa clicks out to 1000 yards and beyond which is where you would see the difference

Re: Heads up on leupold scopes (MOA vs IPHY)

My gunsmith was the one that actually pointed it out to me and then I called leupold to comfirm. Call leupold and ask I would actually appreciate a second conformation, Im hoping that something is just confused as I like the scope but really want MOA vs IPHY

Re: Heads up on leupold scopes (MOA vs IPHY)

Hmmm... the guy I talked was so sure that he has a manager calling me to work out how to handle this. Guess I'll call again and see if I get another tec. I just talked to them again and they said the same thing. I asked why two tecs would say something different and he said that they are basically the same but there would be a difference at longer range. Ahh Im so confused right now. You asked him specically if they were MOA and not IPHY?

Re: Heads up on leupold scopes (MOA vs IPHY)

I have a friend, now retired, who was an engineer at Leupold. He states that since day one the sporting scopes were set up to adjust in MOA. It is the only internationally accepted unit of angular measurement. The mil adjustments came latter.

Just guessing the tech line guys have very limited knowledge to do their jobs. That is to determine if your scope is broken or to read the manual to us over the phone.

Something to consider.
Assuming one of the least likely choices for long range hunting but still used. The 308 Win using 168 grain FGMM ammo.

Exbal
States:
At 500 yards 12.5 MOA x 1.0472 x 5 = 65.45” drop
IPHY 12.5 x1” x 5 = 62.5” drop. 2.95 inches of drop difference.
Not much on big game.

At 1000 is states correction in MOA to get to 1000 yards is 41.5 MOA x 1.0472" = 43.4588" elevation x 10 = 434.59 inches of drop
If you used 41.5 IPHY x 1” x10 = 415” drop
This makes a drop difference is of 1.9588" x 10 = 19.5” drop difference.
On a .308 Win. At 1000 yards this is a 19.5” difference in drop. Enough to cause a big miss. On a flatter shooting gun it’s much less.

Reason for correction.
Corrected my math.
