Cartridge Identification Procedures

To identify an unknown cartridge or a fired cartridge case with the aid of this guide, all that is needed is an accurate measuring device. Since all measurements are given in metric units, a vernier caliper that reads to 0.1 mm is entirely adequate in an emergency a metric scale that reads to 0.5 mm may be used. Calipers or micrometers graduated in inches will also serve, provided that the measurements are converted to metric units. Since 1 inch is equal to 25.4 mm, the inch measurement (in...

Primer Body

Electric primers contain, instead of a percussion element, either a conductive primer mixture or a bridge wire embedded in the ignition mixture. A firing current (normally 24 to 28 V dc) is conducted through a contact on the cartridge base to the conductive ignition mixture or bridge wire, and returns through the cartridge case and chamber wall. This current ignites the primer mixture and initiates the propelling charge. Electric primers may be designed to be pressed into, or threaded into,...

Country Marking Practices

Postwar Czechoslovak cartridge manufacture has followed Soviet practice in calibers and functional types, with the exception of cartridges for the twin 30-mm AA gun, Model 53 70. Czechoslovak ammunition can be recognized by the characteristic factory code composed of three lowercase letters, which resembles, but is different from, the letter code used by Germany during World War II. Cartridge cases (and other items as well) may carry a crosscd-sword mark (see view C in fig 7). (1)...

30x155b Headstamp

This cartridge is the result of postwar French exploitation of the World War II Mauser MK213 gun and cartridge. It was developed during the 1950s for the French revolver-type aircraft gun, Type 3CGF, which was redesignated the DEFA 541. The cartridge can be identified by its electric-primed brass case with a French-style headstamp that includes the designation 3CGF. The gun and cartridge were soon replaced in service by the more powerful 30x113B DEFA 550-series gun and ammunition the DEFA 541...

Cartridgecase Outline Orawings

Cartridge-case outlines are presented in this section in sequence of case length, as indicated by the second element of the metric designation. These drawings will be found particularly useful for identifying fired cartridge cases with dented or deformed mouths, which may prevent ready measurement of the case-mouth diameter. Because of space limitations, the outline drawings are reduced in scale. Cartridge cases 200 mm and less in length are shown at 75 of full size, while cases over 200 mm in...

Kzd Series Fuze

Oerlikon developed this high-performance AA gun cartridge in the early 1960s. Two cartridge case types are known cases with a link positioning groove below the case shoulder are intended for use in the indexing feed belt of the KDA gun, but can be used in all models. This type of case is in current production. Cases without the belt groove were made for use only in the KDB and KDC guns. Cartridge types include HEI and HEI-T APHE and APDS-T WC . HE projectiles have a PDSD fuze, Model KZD-242 or...

37x263r Ammunition

Designed before World War II for the single-shot 37-mm AT gun M3 M3A1 , and used in tank guns of the M5 and M6 series on prewar light tanks, this cartridge resembles the preceding 37x222SR cartridge the two types, however, are not interchangeable. Aside from the cartridge rimt this case can be identified by the Ml 6 cartridge-case designation that appears in the headstamp. The gun and ammunition were obsolete in the US service before the end of World War II, but some may be found in use...

UK 20-mm cartridge-case markings. a. General. Cartridges made in the United Kingdom present a diversity of markings, reflecting the period of manufacture, using arm or service, and type of weapon. Markings indicating model designation, functional type, and producer may be found on the fuze, projectile body, cartridge case, and heads tamp. 1 Cartridge headstamp markings will vary, depending on whether the cartridge was produced for government use or for commercial sale to foreign...

Two nomenclature and marking systems are in use for Soviet cartridges in the 20- to 40-mm caliber range. All cartridges below 25 mm in caliber, and the 30x152B and 37x155 aircraft gun cartridges as well, are identified as to functional type in the same way as small-arms ammunition, by a two-letter or three-letter cyrillic designator. In the second system, AA gun cartridges such as the 25x205SR, 25x218, and 37x253R calibers follow the practice for larger-caliber artillery ammunition....

This Soviet-developed cartridge is used in the N-37 aircraft gun, introduced in the 1950s and still in use. HE I Type OZT and AP-T Type BZT cartridges are known. Soviet-made cartridges have brass cases that carry the designation H-37 N-37 and other data containing Cyrillic letters stenciled on the case wall. The cartridge headstamp is also of the Soviet type. This cartridge is also made by Czechoslovakia, using lacquered steel cartridge cases that carry the...

37x380r Granate

Other Designation 37-mm Bofors Ml939 AA gun. This cartridge is known to have been produced by Bofors in 1939 and by Denmark in 1940, but how long the gun and ammunition were made is a question. Probably they could not compete with the Bofors 40-mm gun performance and were soon dropped. Both HE-T and AP-T cartridges are reported. Developed in Germany before World War II, this high-performance cartridge was used in the naval AA gun, Model C-30. This gun and cartridge were used during World War...

Notes

Cartridges for the Lahti 20x113 aircraft gun, the Swedish 20xl45R antiaircraft AA gun, and for Madsen 20-mm and 23-mm automatic guns, have an exceptionally thick extracting rim, approximately 4 mm thick. 5. The cartridge case has a blow-out venturi in its base, for use in rccoilless rifles. 6. Cartridges for obsolete VYa aircraft guns and for tank subcaliber guns have brass cases. Cartridges for ZU-23 and ZSU-23-4 AA guns have steel cases. Despite their dimensional similarity, the steel-case...

Other Designations 37-mm M1916 37-mm M63 Mod 1. This cartridge and its gun were adopted by the United States in 1916 for infantry use as an adaptation, with very few changes, of a lightweight, man-portable French field howitzer. Although replaced before World War II for combat use, the Ml916 cartridge continued in service for subcaliber training with larger artillery pieces and for firing salutes. US-made cartridge cases can be identified by the gun designation Model of 1916 or the case...

Other Designation 25-mm Soviet naval AA gun. This rimless cartridge is fired in the Soviet naval twin AA gun systems, Models 2-M3 and 2-M8. Two types of projectiles have been noted the older type, with three copper rotating bands, is identical to projectiles for the 25x205SR gun. The rearmost rotating band is inserted into the mouth of the brass cartridge case, which is crimped just to the rear of the middle rotating band. Newer-pattern HEI-T projectiles with MG-25 fuzes have two coppcr...

1 Rimmed cartridge cases have a rim, or extractor flange, extending beyond the cartridge body the rim seats against the breech face and aids in extracting the fired case. There may be a slight undercut or groove in the case body ahead of the rim. 2 Rimless cases have an extraction groove in the case body, leaving a flange at the base of the case. The diameter of this flange is the same as, or very close to, the diameter of the cartridge case ahead of the groove. 3 Semirimmed cases have an...
