The 30-06 Springfield cartridge (pronounced “thirty-ought-six”, "thirty-oh-six") or 7.62×63mm in metric notation, was introduced to the United States Army in 1906 (hence “06”) where it was in use until the late 1970s. It remains a very popular sporting round, with ammunition produced by all major manufacturers.
The .30-06 Springfield cartridge case can hold 68.2 grains and has a volume of 4.42 millilitres (0.270 in 3). The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action rifles and machine guns alike, under extreme conditions.

In 1953, large batches of .30-06 ammunition were manufactured under unique arsenal headstamps. [4] The case had red lacquer sealant around the primer annulus. [4] The headstamp has a two-letter manufacturer code (10- and 2-o'clock) and the lot code (rather than the year) is the number 40 (at 4 o'clock) followed by a third numeral (at 8 o'clock ...
Some rimless cartridges are necked down, and they are positioned by the cartridge's shoulder. An example is the .30-06 Springfield. Pistol cartridges may be located by the end of the brass case. An example is the .45 ACP. A belted cartridge has a larger diameter band of thick metal
The .30-06 Springfield cartridge (7.62×63mm), with its higher service pressure and case capacity, will outperform the 7.62×54mmR when same-length test barrels are used, though this is very uncommon as .30-06 Springfield firearms are generally sold with much shorter barrels than 7.62×54mmR firearms.

The .30-06 Springfield M1906 service ammunition long-range performance was originally overstated. When the M1906 cartridge was developed, the range tests had been done to only 1,800 yd (1,646 m); distances beyond that were estimated, but the estimate for extreme range was wrong by almost 40 percent.

Although military surplus rifles in .303 British were widely available in Canada, the .30-30 was so common that for many years the Hudson Bay Company and other stores in remote areas stocked only .30-30 ammunition. [21] The .30-30 is commonly seen as usable on deer up to 150 to 200 yards. [22]
The .30 caliber Carbine ammunition was also far cheaper to produce than the standard .30-06 ammunition; used fewer resources, was smaller, lighter and easier to make. These were major factors in the United States military decision to adopt the M1 carbine, especially when considering the vast numbers of weapons and ammunition manufactured and ...
