Nikon BDC (Bullet Drop Compensating) reticle is actually a trajectory-compensating reticle designed and calibrated to provide fast, simple aiming points for various shot distances. This unique system integrates a series of small “ballistic circles”—each subtending 2” @ 100 yards—allowing unimpeded lines of sight to even small targets.

Nikon’s BDC is designed to be used with most standard center fire cartridges with typical bullet weights, providing aiming points out to 500 yards, with a 100-yard sight-in. With Magnum cartridges and typical bullet weights, the same scopes with BDC reticles offer aiming points out to 600 yards, with a 200-yard sight-in.

After sighting-in the crosshair at 100 or 200 yards with the highest magnification, determine the distance to the target and use the appropriate ballistic circle. Verify the aiming points by shooting at actual, measured distances.
