Standard BDC
The standard BDC reticle is designed for use with either of the following cartridge categories. Please note that we highly recommend
polymer tipped bullets for long range shooting as they are more aero-dynamic and tend to provide a  atter trajectory.
Standard Velocity – Cartridges with a muzzle velocity of approximately 853 m/s (2800 fps (feet per second)).
We recommend that you zero the  rearm at 91 m (100 yd.) with standard velocity cartridges, this would provide bullet drop compensation
for 183, 274, 366 and 457 m (200, 300, 400 and 500 yd.) using the respective ballistic circles as shown in the  gure to the right.
Magnum Velocity – Cartridges with a muzzle velocity of approximately 914 m/s (3000 fps).
We recommend that you zero the  rearm at 183 m (200 yd.) with magnum velocity cartridges, this would provide bullet drop compensa-
tion for 274, 366, 457 and 549 m (300, 400, 500 and 600 yd.) using the respective ballistic circles as shown right.
Please note that your  rearm may or may not match the information listed for bullet drop based upon the variables listed in this section.

Maintenance
(1) Lens cleaning
To remove dirt or fingerprints, soak gauze or lens cleaning paper (silicon-free paper sold at camera retailers) with a small quantity of absolute alcohol (available from drugstores) and lightly wipe off the affected areas.
Wiping with a handkerchief or leather may damage the lens surface and is not recommended.
Dust may scratch the lens surface or corrode the lens.
Brush dust off using a soft oil-free brush.
(2) Scope exterior
Use a soft dry cloth to wipe off any dirt or fingerprints that might accumulate.
It is not necessary to oil the scope's surface.
(3) Windage/elevation adjustments
These adjustments are permanently lubricated. Do not attempt to lubricate them. Cover them with the caps supplied, except when adjusting them, to keep out dust and dirt.
(4) Eyepiece adjustment
This adjustment is permanently lubricated. Do not attempt to lubricate it.
