  • Rifle mounted ballistic chart
    Patent number: 5546691
    Abstract: A cylindrical casing holds a spring mounted tape upon which is printed ballistic information. The user mounts the casing on a rifle and lines up a shot. While the rifle is in line to be fired, the user, with their trigger hand, extracts the tape from the casing to verify the ballistics of a projectile fired from the weapon by pulling a ring located at the end of the tape. Once the ballistic information is obtained, the user releases the ring which allows the tape to be retracted into the casing.
