Re: Leupold B&C scopes
I have a 4-14 with that reticle - gives you multiple aiming points but requires that you shoot your rifle to get accurate hold-offs. Utilizes two settings, (done by selecting a magnification) so you can tailor the hold-offs to your cartridge a bit. No real advantage over mildots, TDS, Ballistic Mildots etc, they all offer multiple hold-off points and hopefully correct spacing to get you reasonably close for hold-offs if you know some distances.
Good luck in your selection.
