ballistic characteristics. If you cannot find your load in the ballistic tables, you can still use the BDC

one group depending upon your tests.
Option 2:
Included with the marked turrets is a blank turret. After your rifle is sighted in at 100 yds, replace the standard
turret with the blank turret. Without adjusting the elevation, shoot the rifle at various distances up to the
