text: Ball, M1 (1925–1937): The M1 has an , 9-degree boat-tailed projectile designed for aerodynamic efficiency. Though it had a lower initial velocity, velocity and energy were greater at longer ranges due to its efficient shape. The harder bullet was made of seven parts lead to one part antimony. The jacket material was changed to gilding metal (an alloy of 95% copper and 5% zinc) to reduce fouling.
  Ball, M2 (1937–1954): With a  bullet based on the profile of the M1906, this cartridge incorporated the gilding-metal jacket of the M1 projectile combined with a slightly heavier, pure-lead core. It had a higher muzzle velocity than either of the earlier cartridges.
  Ball, M2 alternate (1943–1945): A wartime economy variant of the ball M2 that used a steel full metal jacket coated with gilding metal to conserve copper and tin.
  Blank, M1906: This cartridge is used to simulate rifle fire. It is derived from the M1903 blank, but with a resized neck. It has a paper bullet that contains a tiny black powder charge to aid in breaking it up.
  Blank, M1909: This cartridge is used to simulate rifle fire. The cartridge is identified by having no bullet, having a cannelure in the neck of the case, and the crimp is sealed by red lacquer. This is still a current cartridge for ceremonial M1 Garands. Modern M1909 blanks are rose-crimped, but they have the same designation.
  Dummy, M40: This cartridge is used for training. The cartridge case has six longitudinal corrugations and there is no primer.
