2021-05-02 00:00:00 1-Shot Ballistics has been updated to provide support for 5 drag models: G1, G5, G6, G7, and G6. The computation engine has been changed to a Point Mass Solver, which utilizes the drag function models developed by Ballistics Research Laboratories. Corrections are available for the Environment (temperature, pressure, altitude, and humidity), Spin Drift, Sight Cant, and the Coriolis Effect. This app comes pre-loaded with several guns, cartridges, scopes and bullets to allow you to explore its capabilities. It also contains cartridge and bullet libraries which you can import to use in configuring your own weapons, or comparing them to one another to assess their relative merits.
