The multiple nomograph system for solving ranging and ballistic problems in firearms includes a series of graphs or nomographs for the determination of a series of factors affecting the ballistic trajectory of a bullet in flight. The nomographs may be placed upon the reticle of a firearm scope, or provided on media external to the scope, as desired. The scope reticle includes at least one aiming point or aim point field to compensate for elevation and windage, with the vertical axis preferably being offset to compensate for precession at longer ranges. Stadia for determining angular target dimension(s) are included on the reticle, with a nomograph for determining apparent distance from the apparent dimensions being provided either on the reticle or external to the scope. Additional nomographs are provided for the determination and compensation of non-level slopes, non-standard density altitudes, and wind correction, either on the reticle or external thereto.
