A gunsight reticle defines a system of dimensioned indicia spaced at specific separations to improve aiming accuracy of a rifle. The indicia include perpendicularly intersecting center vertical and center horizontal hairlines, and four horizontal range-marker lines disposed at specific angular separations below the horizontal hairline in bisected relationship with the center vertical hairline. Spacing of the range marker lines below the center horizontal hairline is proportional to bullet drop at selected ranges, depending upon ballistic characteristics of bullet used. Relative lengths of said range-marker bars on each side of the central vertical crosshair are proportional to a cross-wind of 10 mph at target range reflected by respective range marker. The method involves employing this reticle to determine distance to target, and using distance thus determined to ascertain a precise aiming point on the reticle. These indicia also have other useful characteristics that allow the shooter to easily mentally calculate corrections for crosswind, moving target and shooting at targets that are above or below the shooter at a significant angle.
