This simple, effective reticle design can be custom tailored for the trajectory of your ammunition. The accuracy circles on the lower vertical crosshair enable you to accurately compensate for bullet drop out to at least five hundred yards with most calibers. Nikon has designed this BDC reticle to blend simplicity with accuracy - a difficult challenge considering the huge number of variables involved in placing a bullet drop compensating scope on a rifle. These would include: • The mounting system and how true it positions the scope to the center-line of the bore • The make, model and caliber of rifle involved • The rifle's condition and inherent accuracy • The ballistics performance of the ammunition - accuracy, velocity, uniformity and bullet characteristics such as ballistics co-efficients. • A final variable is you - the shooter!
