text: United States The .30-06 round was replaced by the 7.62×51mm NATO round in 1954. However, it remained in limited use in the army reserves and national guard for some time; Frankford Arsenal only stopped production in 1961, and Lake City Army Ammunition Plant was making .30-06 until the late 1970s, with new production batches in 1993 and 2002.
  The "T" (Trials) designation is the code number it had when it was under development and testing. The "M" (Model) designation is the number it received when it was made standard-issue. Issued bullets before 1934 used the year of adoption as their model number.
  Armor-piercing, M1917: The M1917 was the first service-issue armor-piercing rifle ammunition used by the US Army. It had a steel core in a lead envelope with a partial cupro-nickel jacket which had an exposed soft tip. The exposed tip was designed to aid in the envelope peeling away on impact to allow the core to strike the target. It had the unintended effect of making the thin lead envelope an expanding bullet. Since expanding bullets were seen as violating the Hague Convention it did not see service in World War I.
  Armor-piercing, M1918: The M1918 was similar to the armor-piercing M1917 round except it had a smooth cannelure near the case-mouth and had a full-metal-jacketed bullet. It replaced the AP M1917 round in service.
