Am I limiting myself if I get a BDC reticle? I'm very interested in the Leupold Mark 6 3-18x44 . It will be going on a LaRue PredatOBR 7.62 (when these get released.) I'm trying to decided beween the Horus H-58 and the CMR-W reticles. If I ever want to use this scope on another caliber rifle, does having the CMR-W reticle limit this use to only a 7.62 rifle? Thoughts and information greatly appreciated.
