Note: Due to the tremendous differences in currently available black

a representative sample. It is very important to learn the ballistics of the
particular loads that you use and match up the correct drop MOAs and
yardages.

If you wish to get the very best accuracy from the Dead-Hold BDC
reticle, you can custom match yardages to the drop hashmarks of the
reticle based on the exact ballistics of the load you are shooting. To do
this, use the online Vortex Long Range Ballistic Calculator (LRBC)
located at www.vortexoptics.com.

Input your load and environmental conditions data
and then open the “Reticles” tab. Selecting the “Dead Hold” reticle
will then allow you to graphically display custom yardage numbers
matching your load and conditions. This graphic can also be printed
as a field reference, if desired. Small, sticky-backed decals for noting
applicable yards (supplied with the riflescope) may also be affixed to
the scope or rifle.
Follow this up with a day at the rifle range to confirm the accuracy of
the yardage numbers you have obtained through the LRBC. You will
then be confident in having the most accurate possible Dead-Hold
BDC reticle.
