An ammunition tracking system. The ammunition tracking system comprises a server having a data storage. The server is configured to receive data corresponding to a symbolic encoded identifier marked on ammunition, receive data corresponding to a purchaser of the ammunition, associate the data corresponding to the symbolic encoded identifier with the data corresponding to the purchaser of the ammunition, receive data corresponding to a retrieved ammunition casing, and compare the data corresponding to the retrieved ammunition casing with the data corresponding to identification of the ammunition. Upon matching the data corresponding to the retrieved ammunition casing with the data corresponding to identification of the ammunition, the server is configured to transmit the data corresponding to the purchaser of the ammunition.

Provided is a centerfire rifle cartridge. A case has a head end, an open mouth end for receiving a projectile, and a central axis. The head end has a base portion substantially conforming to that of a .50 BMG cartridge. The case has a case wall with a taper of up to 1.0 relative to the central axis. A frusto-conical shoulder portion extends from the case wall and has an angle of approximately 40 relative to the central axis. A neck portion extends from the shoulder portion and has a mouth sized to receive a .375 caliber (9.5 mm) projectile.
