list of military headstamps

A headstamp is the markings on the bottom of a cartridge case designed for a firearm. It usually tells who manufactured the case. Military headstamps usually have only the year of manufacture .

A letter, number, or alphanumeric code indicates the place of manufacture: Other codes may indicate metal suppliers (like France or The Netherlands) or the percentage of copper in the alloy the cartridge case is made of (like Poland and Germany).

United States military cartridges

US arsenals

World War II manufactured cartridges with a single "4" as the year of production were made in 1944. The demand was so great for cartridges that most manufacturers just ground off the "3" on the "43" stamp to save time. Most wartime plants were closed by the end of the war. Some cartridges with a single "5" were made in 1955.

*NM National Match. Match ammunition specially made for the Camp Perry National Rifle and Pistol shooting matches.

Special cartridges

7.92mm Mauser

During World War II the Western Cartridge Company made 7.92mm Mauser ammunition for the Chinese Nationalists. The original Ball bullets made in 1942 had Gilding-Metal-clad jackets and the later Alternate Ball versions made from 1943 to 1944 had Gilding-Metal-Coated-Steel (GMCS) jackets. The Chinese numbers 七 (''Qi'', or "7") over 九 (''Jiǔ'', or "9") at the 9 o'clock position represent the bullet's caliber (7.9mm). The Chinese character 美 (''Měi'', or "Beautiful") at the 3 o'clock position is short for 美国 (''Měi-guó'', "Beautiful Country"). (This was the term Chinese immigrants gave California in the 19th century – and, by extension, the United States). The 2-digit year of production (42, 43 or 44) is at the 6 o'clock position. The ammunition was bulk-packed in standard 20-round cartons without stripper clips to maximize the amounts delivered and the packaging was marked in the Chinese language. In 1944 there was a contract to make 30-million modified Springfield-type Mauser-compatible stripper clips which were bulk-packed in ammo cans. Due to the long transport times, the rough and mountainous terrain, and constantly changing battlelines, the order wasn't completely delivered until 1947.

.30 Caliber (.30-06 Springfield)

In 1953, large batches of .30-06 ammunition were manufactured under unique arsenal headstamps.''Small-Caliber Ammunition Identification Guide (U) Volume 1'' (DST-1160G-514-81-Vol1) The case had red lacquer sealant around the primer annulus. The headstamp has a two-letter manufacturer code and the lot code (rather than the year) is the number 40 followed by a third numeral. Collectors allege that the cartridges were intended to be aid to anti-Communist insurgents and Allied forces equipped with US weapons.
*AN 40# Twin Cities Ordnance Plant, Minneapolis, Minnesota.
*BN 40# St. Louis Ordnance Plant, St. Louis, Missouri.
*CN 40# Lake City Ordnance Plant, Independence, Missouri.

7.62×39mm M43 Soviet

During the Vietnam War in the early 1970s (July, 1970 to January, 1972) the Lake City Ordnance Plant (code: LC) and Frankfort Arsenal (code: FA) produced unmarked Boxer-primed 7.62×39mm Blank and Ball cartridges for use by American and Allied personnel. The blanks were used by the "Tigerland" simulation exercise at Fort Polk, Louisiana. The ball ammunition allowed reconnaissance and Special Operations units to utilize captured Communist Bloc weapons like the SKS carbine and AKM assault rifle. Most ball ammunition went to support Marshal Lon Nol's Cambodian Army (1970–1975), which was receiving reconditioned SKS carbines and AK-47s as military aid.

The cartridges were based on a Lapua design. The bullets had Gilding Metal (GM) or Gilding Metal Coated Steel (GMCS) jackets and Gilding Metal-clad brass cases. Lake City cartridges had red sealant on the primer annulus and Frankfort Arsenal used purple sealant. They came in 20-round cartons that were marked with special short batch numbers that lacked the contractor code and date.

Afterwards Bell Laboratories (code: BEL) made batches of 7.62×39mm ammo in the 1970s and 1980s for training soldiers in the familiarization and use of Communist Bloc weapons. They can be identified by the light-blue sealant used on the primer annulus.

Notes:
:Early French headstamps mark the bullet type at 12 o'clock (eg., ART.D), the 1-digit Quarter of production at 9 o'clock, and the 2-digit Year of production at 3 o'clock. The codes for the manufacturer (e.g. A.RS) and metal producer (e.g. S) are conjoined at 6 o'clock (i.e, A.RS.S).
:Later French headstamps mark the 1-digit Quarter of the year of production and 2-digit Year at the 12-o'clock position (e.g. Q-YY), the letter code for the metal supplier for the case at the 3-o'clock position, the cartridge caliber and model at the 6-o'clock position, and the manufacturer at the 9-o'clock position. They are oriented so that the 12 o'clock and 6 o'clock sides are at right angles to the 9 o'clock and 3 o'clock sides.

;(?-1919)
All loading, assembly and packing of ammunition took place at Spandau Arsenal. Peacetime headstamps had the 2-digit year of production at 3 o'clock, month of production at 9 o'clock, and content case manufacturer (''S'' for Spandau or ''P'' for Polte) at 6 o'clock. Wartime headstamps had the 2-digit year of production at 12 o'clock, case type (S67 = Brass made with 67% copper) at 3 o'clock, content case manufacturer at 6 o'clock, and the batch number at 9 o'clock.

The carton label had three lines of text. The first line would be made up of the bullet type, cartridge assembly and packing facility (''Mf.'' for Spandau's ''Munitionsfabrik''), followed by the date of assembly (in the format MM.DD.YY; 2-digit Month, the Day, and 2-digit Year). The second line concerned the propellant manufacturer (''P.'' for Spandau's ''Pulverfabrik'' or ''Tr.'' for the powdermill at Troisdorf). The third line listed the model of primer (''Zdh'', or ''zundhuetchen''), the date of manufacture, and the manufacturer; an "X" between the primer type and date of manufacture indicated it was a type of primer with a low mercury content.
* C ''Munitionsfabrik Cassel'' ("Ammunition Factory at Kassel") – Kassel, Hesse-Nassau, Germany. Closed after the war. Old wartime-manufactured batches of catridges were still being loaded in the early 1920s by German cartridge-manufacturers who bought up the remaining stock. (They had a declaration on the label that attested that they were old production, to prevent accusations they circumvented the Versailles Treaty).
* S ''Kaiserlich Munitionsfabrik'' ("Imperial russianMunitions Factory") (1722–1919) – Spandau Arsenal, Spandau, Berlin, Germany. Manufactured 7.92mm Mauser ammunition. It was decommissioned in 1919 and was no longer allowed to manufacture war materiel. Gustav Genschow & Co. (GECO) bought the facility in 1924 and used it to make .22-caliber target rifles. GECO loaded cartridges with wartime-manufactured Spandau cases, presumably ones they picked up when they bought the facility.
** Mf. ''Munitionsfabrik'' – The portions of Spandau arsenal dedicated to making cartridge cases and bullets, assembling full cartridges, and packing them into cartons and crates. This would be found in the middle of the first line of the ammo carton label, followed by F1, F2 or F3 (the number of the assembly line that assembled the ammunition).

;P-Codes (1926–1941)
The German government adopted coded headstamps for military ammunition to keep the identity of their suppliers secret. This was briefly continued during the early war and included factories in occupied countries. It was a subterfuge to pretend that Polte manufactured the items.

Headstamps had the cartridge manufacturer's P-code at 12 o'clock, the cartridge case type (e.g., ''S*'' for brass) at 3 o'clock, the Lot number at 6 o'clock, and the 2-digit year of production at 9 o'clock. Steel-cased ammunition had a combined code at the 3 o'clock position that was composed of the Roman numeral code for the steel mill (I through XXIII), the lower-case letter code for the firm that plated the cases (a through z?), and the composition of the steel alloy used (1 through 17). (e.g., IXw1).

''R SD'' is at 10 o'clock, the 2-digit year is at 2 o'clock, and the metric caliber is at 6 o'clock. The "L" prefix to the metric caliber means "long" (i.e., L 5,56 or L 7,62×54mm).
* U ''Viromet S.A.'' (1936–1942; 1949–1991; 1991–present) – Victoria, Romania. A factory initially conceived by the Romanian military to make locally produced smokeless propellants. The military's proposal was approved in 1936 and government permission and planning were provided in 1937. The German firm Ferrostaal was contracted to build it in the hamlet of Ucea in the town of Victoria and provide technical assistance. Work began in 1939 but was stopped in 1942 due to wartime austerity measures. The contract was cancelled in 1944 when Romania declared war on Germany. In 1949 it was finished, reopened and renamed to ''Fabricile Ucea'' ("Factories at Ucea"). In the 1970s it started making its own primers, detonator caps, and fuses. Gradually it diversified from explosives and propellants to making refined chemicals, synthetic resins, and processed plastics. In 1991 its explosives, propellants and fuses division was spun off and renamed S.C Pirochim Victoria S.A, made a division of ROMARM, and transferred under R.A. Rompiro Făgăraş. The remainder of Viromet S.A. was reorganized and then placed under control by InterAgro S.A.

The ammunition production machinery and tool shop were moved to an underground vault under the National Bank and the other machinery was dispersed to the surrounding towns. An explosion on November 22, 1941, that killed 130 workers forced its closure. The factory moved back to the FOMU facility in 1944. It was renamed ''Prvi Partizanki zavod ad Užice'' (PPU) on September 5, 1947.

Singapore (32)

*CHJ ''Chartered Industries of Singapore'' (1967–2000) – Singapore. The headstamp used a letter code for the date (O = 0, A = 1, etc.; "J" is used instead of "I"): the first two letters were the last two digits of the year and the third was the letter 'B' for " Berdan primed". FJ B would be 1969, GG B would be 1977, and JH would be 1998. When the company switched to Boxer primed cartridges in the 1980s, the third letter was dropped. Chartered Industries was merged with ST Kinetics in 2000.

Sweden (65)

Amf stands for ''Ammunitionsfabrik'' ("Ammunition Factory"). They used a royal crown at the 12 o'clock position for government-manufactured or foreign-contracted ammunition; this was left blank if it was made by a private Swedish contractor. The 2-digit year is displayed at the 9 o'clock (tens) and 3 o'clock (ones) positions, and the contractor letter or number at the 6 o'clock position. Early ammunition had a 4-digit year with the first 2 digits (thousands and hundreds) at 9 o'clock and the second 2 digits (tens and ones) at 3 o'clock. Ammunition with an E at the 12 o'clock position (which stands for ''Ersättning'', or "Substitute") have a bimetallic cartridge-case (brass-clad steel) due to wartime economy measures during World War II.

The component manufacturers were marked on the packaging. Kbr. stood for Karlsborg and Mbr. stood for Marieberg, the government ammunition factories. Åker or Åbr. stood for ''Åkersberga'', the government powdermill. ''Tillverkade'' ("assembled by") is the final manufacturer of the assembled cartridges; ''Krut'' ("gunpowder") is the propellant manufacturer, ''Hylsor'' ("cases") is the cartridge case manufacturer, ''Tändh'' ("primers") is the primer manufacturer, and ''Kulor'' ("balls") is the bullet manufacturer.

''Parti'' ("Lot") is the Lot Number. The old method was made up of the 1-letter arsenal code (usually preceded by AMF), the lot number and 2-digit year of production, and the day and month of manufacture. (example: AMF K p3/43 2-3 is ''Amf Karlsborg - Lot #003 - 1943 - 2nd of March''). The new method is made up of the 1-letter arsenal or 3-digit contractor code, 2-digit manufacturing year, and 3-digit (or larger) lot number, followed by the day and month of manufacture. (example: 02762614 24/08 is ''Amf 27 (ÅB Norma), 1962, Lot #614, 24th of August'').

Foreign ammunition producers included ''Deutschen Waffen- und Munitionsfabrik'' (DWM) of Germany; ''Hirtenberger Patronen-, Zündhütchen- und Metallwarenfabrik A.G.'' (HP) and Keller & Co (KC or K&C) of Austria; ''Société Française des Munitions'' (SFM) of France; and ''Valtion Patruunatehdas'' (VPT) of Finland. The ammunition was repacked in Swedish-made packaging to keep the contractors anonymous.

''Tändsticksfabrik'' means "Matchstick Factory". The government contracted match factories to manufacture gunpowder and pyrotechnic fillers like tracers. This was to prevent foreign supplies from being cut off due to embargo or war. It not only made Sweden self-sufficient but helped local industries by giving them government contracts.

Albania (59)

The headstamp used the reverse of the regular ComBloc headstamp code, with the "3" at 6 o'clock and the two-digit year at 12 o'clock. The country was informally allied with China from 1961 and formally withdrew from the Warsaw Pact in 1968. Most of the ammunition used by the Albanian armed forces was imported from China, as it was better quality and cheaper than domestic production. Since 2001 it has been involved in disposing of both domestic and foreign munitions for the UN and NATO.
* 1 ''Uzina Mekanike'' (UM) ''Gramsh'' ("Engineering Factory" in Gramsh) (1962–present) – Gramsh, Elbasan county, central region, Albania. Armory.

Bulgaria (50)

Bulgaria is now a NATO member. It often manufactures ammunition for other NATO partners.
*((10)) Factory 10 (1947–present) – Kazanlak, Bulgaria. Manufactured ammunition and clips. A double ring was added around the number so that it would not be confused with the defunct Russian Factory 10 ammo plant. It was named the Universal Industrial Plant "Friedrich Engels" from 1964 to 1977 and the Машиностроителен Комбинат «Фридрих Енгелс» (''Mashinostroitelen Kombinat "Fridrikh Engels"'', "Fridrikh Engels" Machine-Building Plant) from 1977 to 1989.

The Cyrillic alphabet headstamp has mistakenly been read as ''B'' or ''A B O'' because of mistranslation by collectors.

Czechoslovakia

Czechoslovakia declared independence from Austro-Hungary in 1918. It was divided into the Czech Republic and Slovakia in 1993.
; Czechoslovakia – Pre-War (1918–1939)
* (M) ''Československé Muniční a Kovodělné Závody A.S.'' ("Czechoslovakian Munitions and Metalworking Factories") (1934–1946) – Bratislava, Czechoslovakia (now Slovakia). The nationalized Georg Roth AG factory. The "M" headstamp is embossed in either a full- or half-circle.
* Ô / SB / Ô Sellier & Bellot – Vlašim, Prague, Czechoslovakia. Made percussion caps from 1825 and metal cartridges from 1870, beginning commercial hunting cartridge production in 1895. On the commercial ammunition headstamps the SB is at the 12 o'clock position. The "O"s (often referred to as "rosettes") are at the 3- and 9-o'clock positions, and the caliber is at 6 o'clock. (Pistol ammo usually had only one "rosette"). The "rosettes" (a reversed arrowhead superimposed atop a circle, representing a rifled gunbarrel) indicate the use of Neroxin non-corrosive primers, S&B's proprietary brand.
* S&B, SB ''Sellier & Bellot'' (1825–1936; 1983–present) – Prague, Czechoslovakia (now Czech Republic). On the headstamp the "S&B" is at the 12 o'clock position. Military ammunition had the 4-digit year of production split between 9 o'clock and 3 o'clock (e.g., 19 and 38 for 1938), and the factory code letter at 6 o'clock. When Riga, the last of its satellite factories, was sold off in 1937 the unified factory code letters SBP were placed at 12 o'clock and the quadrant at 6 o'clock were replaced with the month of production in Roman numerals (e.g., VI for June, the sixth month). The headstamp was changed back to S&B in 1983.
** SBP, SB / P ''Sellier & Bellot – Prague'' (1936–1939; 1939–46; 1946?–1983) – Prague, Czechoslovakia. Manufacturing moved to Vlasim in the mid-1930s (starting up in 1936) but the international headquarters remained in Prague. The civilian headstamp has the "SBP" at 12 o'clock and the caliber at 6 o'clock. On the military headstamp the "SB" is at 12 o'clock and the "P" is at 6 o'clock.
** SBR, SB / R ''Sellier & Bellot – Riga'' (1884–1937; 1937–1940; 1940–1941 & 1944–1946) – Krusenhof, Riga, Latvia. A satellite factory set up for sales to Northern Europe and the Baltic region. The civilian headstamp has the "SBR" at 12 o'clock and the caliber at 6 o'clock. On the military headstamp the "SB" is at 12 o'clock and the "R" is at 6 o'clock. It manufactured 7,92mm Mauser and .303 British military ammunition because most of the regional powers used either captured German or Austrian war surplus or British military aid. It was bought out in 1937 by Vairogs (Latvian > "Shield"), a Latvian train-car manufacturing company (formerly ''Fenikss'' (Latvian > "Phoenix") until 1936) that had diversified into automobile production. Vairogs used a stylized "V" as its headstamp from 1937 to 1940. It was later seized and nationalized by the Soviet Union in 1940 and renamed Factory 520 (with "520" as its headstamp). It manufactured 7.62×54mmR M91 Russian rifle ammunition until the machinery was evacuated to Sverdlovsk in 1941. It was returned in 1944/1945 and briefly was in operation until 1946. The facility was then repurposed into a train car factory.
** SBS, SB / S ''Sellier & Bellot – Schönebeck'' (1829–1922) – Schönebeck, Germany. A satellite factory set up initially for production of mercury fulminate. This was due to pollution restrictions placed on the Prague site until 1841. The civilian headstamp has the "SBS" at 12 o'clock and the caliber at 6 o'clock. On the military headstamp the "SB" is at 12 o'clock and the "S" is at 6 o'clock. Sold to the Steyr-Werke A.G. of Vienna, Austria in 1922.
** SB / Schönebeck, P69 ''Sellier & Bellot – Schönebeck'' (1922–1945) – Schönebeck, Germany. The "SB" was at 12 o'clock and the text for ''Schönebeck'' occupied the lower half of the headstamp. The month of production was on the left of the ''SB'' and the two-digit year was to the right. Production was initially by Steyr-Werke A.G. and a group of other Austrian investors. It was eventually bought out by senior investor Fritz Mandl of Hirtenberger A.G. in 1930. The plant was confiscated from Mandl by the German government in 1933 because he was a Jew.

Ethiopia

The first domestic ammunition plant was set up by Emperor Menelik II in 1911. It made 10.75mm M1870 Russian Berdan Mk.2 and 7.62mm M1891 Russian Mosin-Nagant cartridges. Ethiopia had long economic ties to Czechoslovakia dating back to the early 20th Century. An ammunition plant was set up by the Czechs in the reign of Empress Zäwditu in the 1920s that produced 7.92mm Mauser cartridges for the new Czech weapons it was importing. A new Czech plant was set up around 1947 to 1953 CE with assistance from the Považské Strojárne factory and was named after the contemporary ruler, Emperor Haile Selassie I. It made 7.92mm Mauser, .30-06 Springfield, and 7.62mm NATO ammunition for the military and .303 British rifle ammunition for the civilian market. Packaging lists the date in the Ethiopian calendar year (7 to 8 years less than that of the Gregorian calendar), while the cartridge headstamp uses the Common Era year.
