Question for you engineers about Leu Varmint hunter reticules Power setting

[robbin]

Question for you engineers out there about Leupold varmint hunter reticules.
I’ve got 5 8.5X20X56 Leupold scopes with the varmint hunter reticules. The MOA difference between the reticules varies with the power setting.
The large and small triangle settings are:
Varmint reticule
large small Triangle
1.81 2.26
4.13 5.16
7.02 8.78
9.35 11.11

They work great, but there is no listing for the MOA change at FULL POWER 20X. I asked Leupold tech service, they gave me a copy of the manual, which of course doesn’t tell you anything expect what the large and small triangles are set at. I don’t have the scopes with me, but I think the small triangle is about 12X and the large is about 16x.

Anybody know what it would actually be at 20x?
Thanks,
Robbin

Emailed Leupold and asked their tech support to ask one of the engineers.

Just got the response, "Our engineers said they don't have that information available"...

If there is a Leupold rep reading this, you should be embarressed.

Nightforce gave me the answer down to the hundreth MOA for their 42 power scope where the MOA lines are set for 22 power...

I'm far from an engineer, but as long as your gun is accurate enough, here's what I'd do....

Set the gun up and shoot at 100 yards using a single aiming point for each line on the reticle. From there you can figure out your drops in inches or MOA, based on the ballistics of your load, from measuring the distance up for each succeeding shot.

Guy over at long range hunting told me how to do it.
Mutilply the MOA by the power/maxpower

So the large triangle on the 200 yard reticule is 15 power the MOA is 1.81
15/19.3(actual max power)=.777

so 1.81 X .777 = 1.41 MOA at full power do that to each MOA and it works.

Anyway, The MOA changes works out to.

FULL large small
1.41 1.81 2.26
3.20 4.13 5.16
5.45 7.02 8.78
7.26 9.35 11.11

It's inversely proportional, as long as the power ring is cald. properly. I'm doing the same thing with 2 mil-dot reticled scopes right now, a 6-18x Buckmasters and 4-16 Center Point. Believe it or not the Center Point is exactly as calcd. at 2.25 IPHY @ 16x. 62.5% (10/16) of the 10x as cald. And it measures properly. The Nikon is the same but it's 12/18=.667 or 66.67%.
