A portable system for facilitating inclined shooting of projectile weapons comprises a ranging system, an inclinometer and a processor. The ranging system measures a line-of sight range distance from a vantage point to a target that is elevated or depressed relative to the vantage point, and the inclinometer measures an inclination angle of a line of sight between the vantage point and the target. Based on information from the rangefinder and inclinometer, the processor determines a predicted altitude-compensated inclined shooting (ACIS) trajectory at the line-of sight range distance for a preselected projectile. The ACIS trajectory is based on a bullet path height correction between a bullet path height at a first altitude and a bullet path height at a second altitude, a range distance of the target from the vantage point, and selected meteorological atmospheric information.
