U.S. Military Ammunition
Since the early 1900s the U.S. military has standardized on a manageable number of types of small arms ammunition. These Olive-Drab.com pages will provide basic information about each major type. Although other ammunition has been used by the U.S. military (e.g. .22 cal., 12 ga. shotshells) the cartridges covered here represent by far the most common in actual usage.
