PF-
Dope is common parlance for "come-ups" or "bullet drop". The trajectory of a bullet can be determined based on it's muzzle velocity and Ballistic Coefficient (changes for every different type/weight of bullet). Alternatively, trajectory can be determined by simple field shooting. Trajectory is also affected by wind, atmospheric pressure, temperature and altitude.
The precision shooter will develop specific tables for his favorite load at varying temps, alts and pressures. Then, when asked to hit a target at, say, 800 yards, he need only refer to the chart, dial in the "dope" on his scope and settle into the rifle.
The Pathfinder allows you to have your stuff wired pretty tight by maintaining the "dope" table right where you need it.
