  • Patent number: 8770481
    Abstract: A ballistic nomograph for determining a firing solution for small arms fire includes a first member and a second member. Alignment of first indicia on the first member with the first indicia on the second member aligns the value of a range to a target with a first environmental condition to align a first adjustment value with an indicator positioned on the first member to provide a firing solution adjustment to a user. A method of determining a firing solution for a small arm by manually manipulating a ballistic nomograph includes determining environmental conditions and aligning the value of a range to a target with a value of environmental condition. The method also includes visually identifying a firing solution adjustment value that corresponds to the particular combination of the range to the target and environmental condition, and making a firing solution adjustment based on the firing solution adjustment value.
