Patent ID: 7905046

Claim:
A telescopic gun sight having an optical system comprising: a forward objective lens element; a rear eyepiece lens element; an intermediate erector lens element; said lens elements being aligned along an optical axis constituting a line of sight and protectively confined within an elongated tubular housing adapted to be securely affixed to an ordnance firing device; and a substantially transparent reticle between said objective and erector lens elements, said reticle having two interconnected grids, a first being a distance-measuring grid constructed of an electrified grid which illuminates a selected intersection to produce an aiming dot, which aiming dot grid is not visible to a shooter except for the aiming dot and which is interconnected to a second reticle having ballistic aiming indicia thereon, said indicia comprising a center vertical straight hairline and a center horizontal straight hairline, said center vertical and center horizontal hairlines intersecting substantially perpendicularly, and a series of primary range-marker indicia disposed below said center horizontal hairline, the vertical spacing of said primary range-marker indicia below said center horizontal hairline being non-evenly spaced and proportional to drop of said ordnance at selectively increased target ranges dependent upon the substantially parabolic flight of real projectiles fired in earth's gravitational field, wherein the spacing of said range-marker indicia below said horizontal center hairline is determined at the gun sight's highest power at one or two hairlines or one and two and three hairlines or one and two and three and four hairlines or one and two and three and four and at least one additional hairlines in a range of −1.2 to −18 inches of subtention at 100 yards, respectively, and at the gun sight's lowest power at one or two hairlines or one and two and three hairlines or one and two and three and four hairlines or one and two and three and four and at least one additional hairlines in a range of −8 to −103 inches of subtention at 100 yards, respectively.
