Abstract
A priming method for rimfire cartridges is disclosed in which a propellant solution is disposed adjacent a centrifugally located primer material in a rimfire cartridge. The solvent is then evaporated to leave a propellant film near the primer material in order to provide slower, more uniform ignition to thereby allow use of propellant powders which would otherwise be too fast or too sensitive.
