PP-Calc (Pellet Path Calculator) is a small application that interpolates (and extrapolates) an airgun pellet's trajectory from the minimum of user input. Essentially, it takes user input of Muzzle Velocity, Zero Range, Scope Height together with (up to) three range/POI pairs in order to calculate the effective Ballistic Coefficient. That done, the effective trajectory is calculated from which various graphs, tables and mil-dot reticle images are prepared. Since the user's input data can never be accurate enough for a ballistically perfect result, a fuzzy-logic algorithm is used to give a practical result.
