Headstamp

Last updated

A headstamp is the markings on the bottom of a cartridge case designed for a firearm. It usually tells who manufactured the case. If it is a civilian case it often also tells the caliber: if it is military, the year of manufacture is often added.

The left cartridge's headstamp says "FC 223 REM" which means that it was made by Federal Cartridge Co. and it is in the caliber ".223 Remington". The cartridge on the right has a headstamp that says "LC 99" with a symbol that consists of a cross in a circle. This cartridge was made in 1999 by the Lake City Army Ammunition Plant, in Independence, Missouri, USA. The symbol on this headstamp means it meets NATO specifications. Two 223 Headstamps.jpg

The headstamp is punched into the base of the cartridge during manufacture. A resource for identifying where the ammunition originated can be found at Cartridge Collectors.

Colombia

INDUMIL Industria Militar [Colombian Military Industry], company owned by the Government of Colombia operate the only authorised manufacturing company that produce weapons and munitions for both the military and civilian markets. Makes 9×19mm NATO [8 gram / 124 grain bullet], 9×19mm Luger [115 grain bullet], 9×19mm Subsonic [158 grain], 9×19mm Factor 132, .223 Remington, 5.56×45mm NATO, .32 Smith&Wesson, .38 Special, and .38 Special Factor 132. They also make several shotgun shells in 12Ga, 16Ga and 20Ga. Pistol & Rifle ammunition uses "IM" as headstamp, the last 2 digits of the year of manufacture and 2 digits for the designation. Revolver and Shotgun shells are stamped as "Indumil" and the calibre.

China

NORINCO (North Industries Corporation) – Beijing, China. Operates several state arsenals that produce weapons and munitions for both the military and civilian markets. Makes the Big Star rimfire and China Sports centerfire ammunition brands. Currently they make 9×18mm Makarov, 9×19mm Parabellum, .45 ACP, .223 Remington [5.56×45mm], 7.62×39mm Soviet, and .308 Winchester [7.62×51mm] ammo.

NORINCO 7.62×39mm Soviet ammunition was banned from importation into the United States in February, 1994. This was due to the fact that the military surplus ammunition couldn't pass the "magnet test". Non-compliant semi-armor-piercing and armor-piercing rounds have steel penetrators or steel cores that will be attracted by a magnet. The NORINCO copper-plated steel-jacketed Full Metal Jacket bullets would be attracted by a magnet – making it hard to distinguish between compliant lead-core and non-compliant steel-cored ammunition.

Arsenals

Ammunition headstamp has the arsenal number and the last 2 digits of the year of manufacture. The following are arsenals known to produce civilian lead-core ammunition.

Manufacturers

Counterfeits

The use of counterfeit ammunition is perplexing, since NORINCO already makes ammunition and sells quite a lot of it. Theories abound: it was made for use by Chinese-backed insurgents, it was designed to get in on the surplus ammo market, or it was designed to make users leery of Western-made surplus ammunition and get them to buy new foreign-made ammo.

Egypt

What appears like "TO" is actually the Arabic letters for Haa (ح) and Mim (م), the first letters of the words for "Military Factory". It is an Egyptian Military property mark, much like the broadshead arrowhead used by the British Government. The larger versions of the symbol has the numbers ٧٢ ("27") inset in the circle split by the vertical line. The "TO" is found on the base of shotgun shells, which Military Factory 27 makes for the civilian hunting market.

Manufacturers

Ammunition Manufacturers' Association (Winchester Repeating Arms Company, US Cartridge Company, Union Metallic Cartridge, and Phoenix Metallic Cartridge Company) [1900-1907]. The 'Big Four' formed a group that cut out any arms companies they saw as a potential threat (like Savage and Western). They refused to make ammunition for them or even sell them the components. It fell apart in 1907 due to internal squabbling. The side-effect is that their methods forced their spurned customers to become rivals who made their own components and assembled their own cartridges. Union Metallic Cartridge got bought out by Remington Arms in 1912, US Cartridge Company was bought out by National Lead Company (who owned Winchester) in 1918, followed by Winchester being bought out by Olin Industries (who owned Western Cartridge) in 1931.

Military Headstamps

Military cartridge headstamps do not usually have the caliber and cartridge name on it. The headstamp may have a 2- or 3-symbol letter, number, or alphanumeric code indicating the place of manufacture. [14] This is usually followed by two digits indicating the last two digits of the year of manufacture; they may have additional digits or a letter indicating the month or yearly quarter of manufacture. The packaging usually has the manufacturer code, 2-digit year, and a lot number on it so bad or suspect batches can be removed.

The .45 ACP, also known as .45 Auto, .45 Automatic, or 11.43×23mm is a rimless straight-walled handgun cartridge designed by John Moses Browning in 1904, for use in his prototype Colt semi-automatic pistol. After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. The round was developed due to a lack of stopping power experienced in the Moro Rebellion in places like Sulu. The issued ammunition, .38 Long Colt, had proved inadequate, motivating the search for a better cartridge. This experience and the Thompson–LaGarde Tests of 1904 led the Army and the Cavalry to decide that a minimum of .45 caliber was required in a new handgun cartridge.

<span class="mw-page-title-main">Rimfire ammunition</span> Type of ammunition that is only commonly found in small-caliber firearms

A rim-fire is a type of metallic cartridge used in firearms where the primer is located within a hollow circumferential rim protruding from the base of its casing. When fired, the gun's firing pin will strike and crush the rim against the edge of the barrel breech, sparking the primer compound within the rim, and in turn ignite the propellant within the case. Invented in 1845 by Louis-Nicolas Flobert, the first rimfire metallic cartridge was the .22 BB Cap cartridge, which consisted of a percussion cap with a bullet attached to the top. While many other different cartridge priming methods have been tried since the early 19th century, such as teat-fire and pinfire, only small caliber rimfire cartridges have survived to the present day with regular use. The .22 Long Rifle rimfire cartridge, introduced in 1887, is by far the most common ammunition found in the world today in terms of units manufactured and sold.
