Simply the mil-dot reticle with line stadia instead of dots (including .5 mil lines as well) providing a total of 17 minutes of trajectory compensation. I've seen this reticle in a friends Leupold, and it has to be the best ballistic and ranging reticle out these days.
FWIW any reticle with at least 1 addtl. stadia out of the optical center of the scope provides some degree of ranging by simply manipulating the mil-ranging formula.
TD Smith of TDS reticle fame had the best and most flexible system for reticle ranging which can be very simply adapted to any multiple stadia reticle design including simple plex, mil-dot, and custom reticles.
