, which had been introduced alongside the .30-03 cartridge, was modified to accept the new .30-06 Springfield cartridge. Modifications to the rifle included shortening the barrel at its breech and resizing the chamber, so that the more tapered bullet would not have to jump too far to reach the rifling. Other changes to the rifle included the elimination of the troublesome "rod bayonet" of the earlier Springfield rifles.
The M1906 maximum range was originally overstated. When the M1906 cartridge was developed, the range tests had been done to only ; distances beyond that were estimated, but the estimate for extreme range was incorrect by almost 40 percent. The range discrepancy became evident during

When those weapons were later replaced with U.S. machine guns firing the M1906 round, the effective range of the barrage was 50 percent less. Firing tests performed around 1918 at Borden Brook Reservoir (Massachusetts), Miami, and Daytona Beach showed the actual maximum range of the M1906 cartridge to be . Germany, which was using the ''S Patrone'' (S ball cartridge) loaded with a similar flat-based bullet in its rifles, had apparently confronted and solved the same problem by developing an aerodynamically more refined bullet for long-range machine gun use. The ''s.S. Patrone'' was introduced in 1914 and used a ''s.S. – schweres Spitzgeschoß'' (heavy spitzer) boat-tail bullet which had a maximum range of approximately .

Cartridge, caliber .30, ball, M2
Wartime surplus totaled over two billion rounds of ammunition. Army regulations called for training use of the oldest ammunition first. As a result, the older .30-06 ammunition was expended for training; stocks of .30 M1 ball ammunition were allowed to slowly grow until all of the older M1906 ammunition had been fired. By 1936, it was discovered that the maximum range of the .30 M1 ball ammunition with its boat-tailed spitzer bullets was beyond the safety limitations of many military firing ranges. An emergency order was made to manufacture quantities of ammunition that matched the external ballistics of the earlier M1906 cartridge as soon as possible. A new cartridge was developed in 1938 that was essentially a duplicate of the old M1906 round, but loaded with
IMR 4895 propellant and a new flat-based bullet that had a gilding metal jacket and a different lead alloy, and weighed instead of . This 1938 pattern cartridge, the cartridge, caliber .30, ball, M2, achieved a muzzle velocity of and muzzle energy of .

In 1938, the unstained, , flat-base bullet combined with the .30-06 case became the M2 ball cartridge. The M2 ball specifications required minimum velocity, measured from the muzzle. M2 ball was the standard-issue ammunition for military rifles and machine guns until it was replaced by the 7.62×51mm NATO round in 1954. For rifle use, M2 ball ammunition proved to be less accurate than the earlier M1 cartridge; even with match rifles, a target group of diameter at using the M2 bullet was considered optimal, and many rifles did not perform nearly as well.

. Loads are available with reduced velocity and pressure as well as increased velocity and pressure for stronger firearms. The .30-06 remains one of the most popular sporting cartridges in the world. Many hunting loads have over of energy at the muzzle and use expanding bullets that can deliver rapid energy transfer to targets.
The table above shows typical muzzle velocities available in commercial 30-06 loads along with the maximum .30-06 muzzle velocities reported by several reloading manuals for common bullet weights. Hodgdon, Nosler, and Barnes report velocities for barrels. Hornady and Speer report velocities for barrels. The data are all for barrels with a twist rate of 1 turn in which is needed to stabilize the heaviest bullets. The higher muzzle velocities reported by Nosler for and heavier bullets use loads employing a slow-burning, double-base powder (Alliant Reloder 22).
The newer
7.62×51mm NATO/.308 Winchester cartridge offers similar performance to standard military .30-06 loadings in a smaller cartridge.
Recoil

Lake City Army Ammunition Plant (LCAAP) is a U.S. government-owned, contractor-operated facility in northeastern Independence, Missouri, that was established by Remington Arms in 1941 to manufacture and test small caliber ammunition for the U.S ...
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.
* Armor-piercing, M1922 (''1922–1934''): This was a redesigned armor-piercing round with a heavier steel core. It was the first armor-piercing round to have a black-painted bullet tip.
* Armor-piercing, M1 (''1934–1939''): This was a higher-velocity (3,180 fps) AP round that was under development throughout its service. It was replaced in 1939 by the AP M2, a redesign of the AP M1922.
* Armor piercing, M2 (''1939–1954''): This cartridge is used against lightly armored vehicles, protective shelters, and personnel, and can be identified by its black bullet tip. Bullet is flat base, weight 163–168 grains. Defense against the M2 projectile by name is one of the performance standards for
Type IV body armor.
* Armor-piercing incendiary, T15/M14 (''1943–?'') and M14A1 (?-1954): This cartridge may be substituted for the M2 armor-piercing round and is normally employed against flammable targets. The tip of the M14 bullet is colored with a blue tip over a black ring. The M14A1 featured an improved core design and incendiary charge and had a silver-colored aluminum-painted tip.
* Ball, M1906 (''1906–1925''): This cartridge is used against personnel and unarmored targets and can be identified by its silver-colored cupro-nickel alloy bullet jacket. The M1906 has a projectile and flat base. Its jacket was found to quickly foul the bore.
* Ball, M1 (''1925–1937''): The M1 has an , nine-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.
* Explosive, T99: Development of a cartridge that contained a small explosive charge that more effectively marked its impact. Often referred to as an "observation explosive" cartridge, it was meant to designate line-of-sight targets for cannon. The T99 was never adopted.
* Frangible, T44/M22 (''April 1945''): The bullet disintegrates upon striking a hard or armored target, leaving a pencil-like mark to indicate a hit during bomber aerial gunnery practice. The bullet is identified by a green tip over a white ring.
* Gallery practice M1919: A reduced-charge Ball cartridge with a 140-grain wax-coated lead round-nosed bullet used for target shooting at indoor facilities or near built-up areas. It was later renamed the ''Guard M1'' in 1933 and was used for guard and sentry duty at defense plants and military installations during World War II.
* Guard M1906 (''1907–1918''): A reduced-charge ball cartridge with a 150-grain FMJ pointed-nose bullet used for guard and sentry duty in built-up areas. The cartridge was originally marked with six cannelures in the middle, but this weakened the case and caused it to burst in a dirty rifle. It was later marked by six dents or flutes on the shoulder of the cartridge. Although production stopped in 1918, there were plenty of stocks of the oddball round left until the 1920s.
* High-pressure test, M1: The cartridge is used to proof test 30-06 rifles and machine guns after manufacture, test, or repair. The cartridge is identified by stannic-stained (silvered) cartridge case loaded to a pressure of .
* Incendiary, M1917: Early incendiary cartridge, bullet had a large cavity in the nose to allow the material to more easily shoot forward on impact. As a result, the M1917 had a tendency to expand on impact. The M1917 had a blackened tip.
* Incendiary, M1918: Variant of the M1917 with a normal bullet profile to comply with
international laws regarding open-tipped expanding bullets.
* Incendiary, M1: This cartridge is used against unarmored, flammable targets. The tip of the bullet is painted blue.
* Match, M72: This cartridge is used in marksmanship competitions, and can be identified by the word ''MATCH'' on the
headstamp

. Ammunition lots loaded for use in specific competitions have been headstamped NM (National Match), IM (International Match), PM or P (
Palma Match), and I & P (International and Palma Matches).
* Rifle Grenade blank, VB (''?-1933''): These cartridges were designed to launch the
Viven-Bessières rifle grenade. The VB rifle grenade was initiated when a Ball bullet passed through it. The Rifle Grenade Blank had a wooden bullet so it could have a reduced danger space when fired. It was used with inert Training/Practice grenades at training ranges that were near built-up areas. It had a "VB"

to indicate its use.
* Rifle Grenade blank cartridges, M1 (''1933–1945''), M2 (''1941''), M3 (''1941–1953''), and M3E1 (''1953–present''): These cartridges are used in conjunction with the M7 series of rifle grenade launchers to propel rifle grenades. Blank cartridges utilize a full-size brass case and carry only a powder charge. M1, M2, and M3 blanks are sealed at the case-mouth with a red wad and the M3E1 is crimped. The differences between the three cartridges have to do with the powder charge and the range of grenade launchers. The M1 was a universal blank and rifle grenade cartridge that replaced the specialized rifle grenade (RG), chemical rifle grenade (CRG), and chemical warfare grenade (CWG) cartridges and was used with cup-discharger rifle grenade launchers. The M2 was an experimental cartridge used as a testbed; it used a propellant mixture of black powder and smokeless powder because it was feared that the smokeless powder would not reliably ignite by itself. The M3 was designed to be used with the M1 series (for the

spigot grenade launchers and used a propellant that was a mixture of five grains of FFFG black powder and 40 grains of IMR-4898 smokeless powder. The M3E1 featured an extended case neck, a rosepetal crimp, and a full smokeless powder loading and was designed for use with the
M7A3 spigot rifle grenade launcher and larger
ENERGA rifle grenade.
The grenade blanks were issued in double-rowed 10-round cartons, usually as part of a set with the hermetically-sealed metal M13 ''grenade launcher assortment'' ammo can.
* Tracer, M1: Tracer for observing fire, signaling, target designation, and incendiary purposes. The M1 has a red tip.
* Tracer, M2: Tracer for observing fire, signaling, target designation, and incendiary purposes. Has a short burn time. The M2 originally had a white tip, but then switched to a red tip like the M1. This was due to the similar purpose of both rounds.
* Tracer, M2 alternate (''1943–1945''): A wartime economy variant of the tracer M2 that used a steel full metal jacket coated with gilding metal. It was ballistically matched to the ball M2 alternate.
* Tracer, T10/M25: Improved tracer over M1 & M2. Designed to be less intense in terms of brightness than either the M1 or M2 tracers. The M25 had an orange tip.

The .30-06 (or "caliber .30") cartridge was adopted in 1940 during the beginnings of the Lend-Lease program in anticipation of using American weapons in front-line service. The British used American-made ammunition during the war, which was designated as ''cartridge S.A, .30'' to avoid confusing it with their own

service round. It was used after the war as belted machinegun ammunition by the Royal Armored Corps and was not declared obsolete until October, 1993. The "z" after the numeral indicates that it used a nitrocellulose propellant rather than cordite. Marks of ammunition were originally designated with Roman numerals (i.e., .303 Ball Mark VII), but were replaced with Arabic numerals by 1945 (i.e., .303 Ball MK 7).
* Cartridge S.A, .30 ball MK Iz: This was the War Ministry's designation for the 172-grain .30-06 Ball M1 round. It was not accepted for use in service, as the American military had already marked it as limited standard.
* Cartridge S.A, .30 ball MK IIz: This was the War Ministry's designation for the 150-grain .30-06 Ball M2 round. Lend-Lease ammo made for the British government had no mark designation and was headstamped ''.300z''.
* Cartridge S.A, .30 ball MK 3z: This was the designation for an experimental round designed in 1945 for Royal Navy use that was based on the .30-06 ball M2. It was not adopted for service.
* Cartridge S.A, .30 ball MK 4z: This is a boat-tailed cartridge with a 150-grain full metal jacketed bullet. It is marked with a purple annulus. It was normally packed in 20-round cartons. However, Commonwealth countries that used the M1 Garand (like Pakistan) bundled it in 16-round cartons that contained two preloaded 8-round Mannlicher-style en-bloc clips.

The .30-06 round was adopted in 1949 for use in American war surplus military aid weapons like the M1 Garand and M1919 medium machinegun. Military production was from the 1950s to the mid-1960s, while export production to French Union nations lasted until the late 1980s. Cartridge cases were softer than US specifications to prohibit their being recovered and reloaded by insurgents.
