What is the purpose of the dot above the crosshair on Leupold custom, ballistically matched reticles?
This dot can be used for range estimating purposes. Certain VX-III scopes offer a Duplex range estimating feature which allows the user to bracket a deer between the center intersection of the reticle and the top post (see your Leupold owner’s handbook for details). Leupold custom, ballistically matched reticles allow the user to estimate the distance to a deer (measuring 18″ from backbone to brisket) using the dot, or the distance to an elk (measuring 26″ from backbone to brisket) using the top heavy post.
