Thank you Q
For some reason, the plane of reticle seems concealed by most scopemakers. Very hard to find out without actually looking through one.
It makes a huge difference to me so I stay away from scopemakers who tip-toe around it.

-A 1st plane reticle stays ~constant in size, regardless of magnification. Great for range estimating reticles as it is always in cal and tracking very accurately at any setting. However, Because the reticle subtension(relative size)stays the same with increasing power, more target area is covered up. European, Tactical.
-A 2nd plane reticle subtension changes with magnification. Great for a precision shooting as the reticle covers less target area with increasing magnification. Used for range estimating only at specific powers.
Tracking accuracy is affected more by power changes. American, Target.
There are other pros/cons, and design attributes, but thats the jist of it.
