ft/s = Velocity in Feet Per Second ft/lb= Energy in Foot-Pounds
PBR = Point Blank Range (calculated for a 1-inch kill zone)
Aiming for the center of the KZ between "Near PBR" and "Far PBR"
should result in a lethal shot and between those ranges, no hold over /under should
be needed. Maximum Range is the distance that the pellet can theoretically travel if it isn't halted by a backstop.
Near Zero is the first range where the pellet will cross the line of sight. Zenith
is the highest point of the trajectory, or the point where the pellet is 1/2 -inch above the line of sight. Far
Zero is the second point where the pellet crosses the line of sight.
