Front Plane, Rear Plane

Europe’s first- or front-plane reticles have become popular in the U.S., otherwise long wedded to second- or rear-plane reticles. A first-plane reticle stays the same size relative to the target across a scope’s power range. Perversely, it can cover small, distant targets at high magnification; and it shrinks to obscurity at the lower power useful for fast shots in thickets! Rear-plane reticles stay the same apparent size across the magnification range. Its dimensions change in relation to the target.
