The new Nikon 6-18x40 rifle scope with BDC (Bullet Drop Compensating) 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 reticle 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.

Mastering the art of long-range shooting has always been one of the greatest challenges for the hunter. Determining the correct hold-point on an animal at long range has a lot to do with the velocity of a cartridge, bullet weight and ballistic coefficient—or science—and little to do with luck or guess work.  While there is no substitute for practice, Nikon’s new BDC reticle—particularly when used with a Nikon Laser Rangefinder—can provide the necessary edge in determining proper shot placement at a variety of known distances.
