Scope height measurement with a tapered base, where?

Just a stupid question…Where the heck would you make the measurement for sight height, with a tapered base?
Seams to me, that it would be the center of the scope. Not on the ends. Any thoughts.

Regards Mike.

I dont own a scope that has the reticle in the center. It is usually well back toward the eye piece. But the center would appear to be a logical place to start. You would just have to remember to add the moa increase from the start if you use a ballistic table or program.

Actually, you don't add the MOA on the base to a ballistics program, at least not the ones I use. The tapered base just allows you to use more of your scopes adjustment to dial up. By mounting on a tapered base, the crosshairs are positioned more to one end of their travel, allowing you to dial up more elevation to shoot the longer ranges...

So how do you measure the height of the scope with a 20moa base?

Center of tube at knobs. That is your reticle center. That won't really change that much with a 20 MOA base vs a flat base, but the angle you're looking down the scope does...that's how you get the extra 20MOA of adjustment on the base...

The input of sight height above the bore just gets you in the ballpark, anyway - you still need to go shoot your drops

I have never seen a reticle located at the knobs. All the scopes I have ever seen has the reticle just in front of the ocular lens behind the knobs.

Which scope has the reticle under the knobs?
