The 10.7×58mmR cartridge used in the Berdan was also invented by Hiram Berdan, with the assistance of Russian colonel Alexander Gorlov . It was the subject of many patents in both the United States and United Kingdom. The bottleneck cartridge case used the Berdan primer, its first use in a small arms cartridge.
Berdan and Boxer primers are used in centerfire cartridges; the primers differ in construction. Various priming mixtures have been used in different sized primers to effect prompt ignition of the powder charge. Particles with relatively high heat capacity are required to promptly ignite smokeless powder deterrent coatings. Some priming ...
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.

This is a historic (index) list of United States Army weapons and materiel, by their Standard Nomenclature List (SNL) group and individual designations — an alpha-numeric nomenclature system used in the United States Army Ordnance Corps Supply Catalogues used from about 1930 to about 1958.
Most surplus ammunition is steel-cased and uses Berdan primers, which effectively hinders its use for handloading. However, with the increased popularity of surplus Eastern-bloc Mosin–Nagant, SVT-40, and PSL rifles in the United States, Boxer-primed ammunition and unfired cases are increasingly available; these cases take large rifle primers.
The primers for the cartridges were non-corrosive because the M1 carbine's gas-system would have fouled or corroded if standard corrosive primers were used. It only came in Grade R ("Rifle") because the M1 Carbine was semi-automatic only, dispensing with the use for Grade 2 for an automatic weapon.
The primer type can be Berdan or Boxer Large Rifle. [24] U.S. Army Research Laboratory (ARL) research papers on the influence of Berdan and Boxer primer spit-hole diameter on 7.62-mm cartridge performance concluded the primary advantage of a Berdan primer is that they are less expensive than a Boxer primer due to their reduced complexity.
