Using the Reticle for Bullet Drop Compensation
Precision BDC Technique
If you wish to get the very best accuracy from the AR-BDC reticle
or work with loads and zeros other than those listed here, you can
custom match the exact ballistics of your particular load to the
drop hashmarks of the reticle using ballistic programs such as our
LRBC (Long Range Ballistics Calculator).
The basic technique is to input your load data and environmental
conditions into the LRBC program and then generate a drop
chart. Select MOAs for the drop display, and choose 10-Yard
Range Increments. Look for MOA drops on the chart that are as
close as possible to the MOA drops shown on the reticle image
below. Then, simply cross reference the listed yardage numbers—
save these yardages for field reference and use.

Using the Reticle for Range Estimation
The AR-BDC reticle can be used to quickly estimate ranges when
viewing objects of known dimensions of either 9” or 18”. To be
accurate, ranging will require the Strike Eagle to be set to 6X
magnification.
Distance will be approximately 100 yards when diameter of circle
pattern matches an 18” object or radius of circle matches a 9”
object.
Distance will be approximately 200 yards when total width of
first horizontal mark matches an 18” object or half width of line
matches a 9” object.
Distance will be approximately 300 yards when total width of
second horizontal mark matches an 18” object or half width of
line matches a 9” object.
Distance will be approximately 400 yards when total width of
third horizontal mark matches an 18” object or half width of line
matches a 9” object.
Distance will be approximately 500 yards when total width of
fourth horizontal mark matches an 18” object or half width of line
matches a 9” object.
Distance will be approximately 600 yards when total width of
fifth horizontal mark matches an 18” object or half width of line
matches a 9” object.
