3.5-10x40, one inch aircraft aluminum tubes. Two focal plain two reticle, four dial system: The two rear dials move the cross hairs that are located in the second focal plain, behind the erector tube. They stay the same size throughout the full magnification range.
The forward two dials control the series of circles that are on the bottom vertical wire in the first focal plane. These circles are used to bracket your intended target, and they get larger through the magnification range. Shepard uses bracketing circles in the first focal plain so that the circles get bigger as the target gets bigger without covering up the target, as with mil dots.
The placement of the etched circles depends upon the velocity of your load. Each Shepard scope is coordinated to the velocity of your rifle.
Shepard scopes are produced by Light Optical company in Japan. When you want to shoot, the bullet drop math is pre-done. Just pick the circle that fits and execute your shooting routine.
