yup. because the scope is elevated above the muzzle, the pellet will "climb" to your zeroed yardage. For instance, if you sight it in at 10 yds, to hit a target 15 yds away you'd have to aim an inch LOWER (I know, threw me for a loop too) I'll plug in your specs with predators and show you on the graph. So if you sight it in at 13.5 yds, the pellet will reach it's zenith (highest point) at 24yds, and then back down to zero at 34.3 yds. That's assuming the pellets are leaving the muzzle at @800fps, and your scope height is 1.5 inches.
