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

Dim Tracers

Dim Tracers cartridge exhibit.

Dim tracers, sometimes called starlight tracers or infrared tracers, emit mostly infrared wavelengths and show little to no visible light when they burn.

Dim tracers help conceal a gunner's location by rendering the tracer stream invisible to the naked eye. Dim tracers also address the problem of night vision devices being overwhelmed by the brightness of traditional tracer rounds.
