land width = and the primer type is Berdan or boxer small pistol. According to the official C.I.P. (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) rulings the 7.62×25mm Tokarev case can handle up to Pmax piezo pressure. In C.I.P. regulated countries every handgun cartridge combo has to be proofed at 130% of this maximum C.I.P. pressure to certify for sale to consumers. This means that 7.62×25mm Tokarev chambered arms in C.I.P. regulated countries are currently (2017) proof tested at PE piezo pressure. Design The cartridge is in principle an enhanced Russian version of the 7.63×25mm Mauser. The Russians produced a wide array of loadings for this cartridge for use in submachine guns. These include armor-piercing, tracer, and incendiary rounds. This cartridge has excellent penetration and can easily defeat lighter ballistic vests (NIJ level I and IIA) as well as some kevlar helmets, such as the American PASGT helmet. When fired from a carbine-length barrel, the cartridge may penetrate NIJ level II, but is sometimes stopped by the current standard armor NIJ level IIIA. (Level IIIA is an advanced version of the Level II that can stop faster bullets than Level II, but does not meet the Level III standard. NIJ standards factor in up to 1400 fps of bullet velocity; higher-velocity rounds can eventually penetrate them, but by definition, level III must be able to stop any 7.65 mm bullet ). Although most firearms chambered in this caliber were declared obsolete and removed from military inventories, some police and special forces units in Russia, Pakistan and China may still use it because of the large quantity of stored ammunition available. There is a common misconception that military surplus 7.62 Tokarev ammunition uses copper-coated mild steel bullets, and that this increases the chance of dangerous ricochets when fired at hard targets and can damage bullet traps often used on shooting ranges. While steel-core ammunition in 7.62×25 is available internationally, in the United States the importation of 7.62×25 cartridges loaded with copper-coated steel bullets is illegal; federal law defines these as armor-piercing pistol ammunition. So-called steel bullets sold are generally lead-core bullets with copper-washed steel jackets, and these do not present a significantly greater risk of ricochet than a standard copper-jacketed projectile. In 2018, 7.62×25 ammunition was available for export from Romania, Czech Republic, Bulgaria, Serbia, and Russia. Reloading Reloadable cartridge cases can be produced by resizing and trimming
