A military small & medium caliber ammunition collection

About the Collection

The cartridge collection consists of military rifle, heavy machine gun, and small- to medium-caliber cannon ammunition. The primary focus is on ammunition up to 35mm caliber made during World War 2 or later, although some specimens do fall outside of these general guidelines.

Within this very broad field, there is a special emphasis on 7.62x51mm NATO, .50 BMG, 30x173mm GAU-8, and experimental ammunition.

Featured Ammunition Exhibit


FN BRG-15 cartridge exhibit.

The FN BRG-15 was a heavy machine gun designed by Fabrique Nationale of Belgium as a potential replacement for the .50 caliber Browning M2 heavy machine gun. Several 15mm cartridge variants were tried as the project evolved, with the 15.5x106mm round being the last in the series. The project was ultimately cancelled in the early 1990s.
