Hello,

I have a Leup. VARI-XIII 4.5 x14 AO scope that was branded Tactical by Leupold in the early/mid 90s. The only thing tactical is the mil-dot retical and target knobs it has. It's also a nice matte finish. Anyways I'm trying to figure out if this scopes adjustments are true moa (1.047) or inch/hundred yards. 

I know we are only talking about half and inch distance at 1000 yards, but how did Leupold make design them? My curiosity is academic and not practical as I really have no way of testing it to that degree of precision. 

Thanks in advance. Great forum you guys have here.

Does the knobs have moa or inches stamped on them anywhere?

Good question. There are no markings and the manual has long ago disappeared. The latest generic manual on their webpage says:

"One-MOA moves the point of impact at 100 yards by 1 inch." Whatever

I'm not sure what that means. I know that for all practical purposes it is IPHY, but.......

If they are true target knobs then even that is not "tactical'.
 
Target knobs are covered by a turret cap which has to be removed in order to see and adjust the reticule. Tactical knobs remain exposed and have a knurly look.
 
Even if the scope says 1/4 inch movement or 1 MOA movement, then it still can adjust more or less and an easy way to check is just to stick a 12 inch ruler up at 100yds. Now sight the scope at the bottom of the ruler and firmly locking the scope in place count how many clicks it takes to get to the top of the ruler. Do the maths from there.
 
Or you can do the same at 25yds and divide the clicks by 4. Use a yard stick, even better.
 
Most of the earlier scopes were 1/4 inch at 100yds.

Thanks for the information. I might try a yardstick and come a full revolution on the sights. If it's moa, then by my math it would be 15.705 inches and if it's IPHY it will be 15. 

Anyway here are a couple of pics. At one point in the early 90s they were selling these to police departments and had them in their tactical catalog.  

Thanks for the help.
