Thank you for choosing the Nikon BDC reticle riflescope. The BDC reticle is designed to compensate for the trajectory of your firearm. Regardless of the particular style of BDC reticle you have, the

En

position of the circles are based upon an average trajectory for some of the more popular projectiles and cartridges on the market based upon the intended use of the scope itself.
Please note that the reticle is based upon ballistic information and may or may not meet the same results for you as there are many variables that come into play such as:

• Actual Velocity (Ammunition manufactures’ information in regards to muzzle velocity may or may not match the velocity your firearm produces. The best way to determine the actual muzzle velocity
for your firearm is to use a chronograph).

• Temperature

• Humidity

• Altitude

• Barometric Pressure

• Condition and inherent accuracy of the firearm

• The mounting system and how true it positions the scope to the centerline of the bore

Note: This manual is not applicable to some reticles that are available in your region.

As you read further into this manual, you will see the suggested parameters in which the reticle was based. These parameters will help you get started in optimizing your setup.

Note: It is imperative that the reticle be level in relation to the firearm. If the reticle is canted, even just a few degrees, it can cause the shot to drift off the centerline of the point of aim. There are many
commercial leveling devices on the market, but the one that we find to be the most accurate in leveling the reticle is a plum bob. Use a bubble level to make sure the firearm is level, then look through
the scope at an appropriately placed plumb bob and align the reticle accordingly.

Please also note that all Nikon BDC reticles were originally designed to be used on the highest magnification. Since changing the magnification changes the position of the circles in relation to
the target, the distances listed along with each of the illustrations are at the highest magnification. The center crosshair does not change with magnification as it is placed in the optical center of the
scope.
