  2. Chamber pressure - Wikipedia

    en.wikipedia.org/wiki/Chamber_pressure

    Within firearms, chamber pressure is the pressure exerted by a cartridge case's outside walls on the inside of a firearm's chamber when the cartridge is fired. The SI unit for chamber pressure is the megapascal (MPa), while the American SAAMI uses the pound per square inch (psi, symbol lbf/in 2) and the European CIP uses bar (1 bar is equal to 0.1 MPa).

  3. Copper units of pressure - Wikipedia

    en.wikipedia.org/wiki/Copper_units_of_pressure

    These terms were adopted by convention to indicate that the pressure values were measured by copper crusher and lead crusher gauges respectively. In recent years, they have been replaced by the adoption of more modern piezoelectric pressure gauges that more accurately measure chamber pressures and generally give significantly higher pressure ...

    Other benefits of the SAAMI conformal transducer are: very adaptive to the high volume quality control testing demands of commercial and law enforcement ammunition production; protection of the transducer from direct exposure to the high temperature combustion gases and hence a comparatively long service life; 80,000 psi (551.6 MPa) maximum ...

  6. Gauge (firearms) - Wikipedia

    en.wikipedia.org/wiki/Gauge_(firearms)

    Due to problems defining a pound, and to get pure lead, the Gun Barrel Proof Act 1855 defined a gauge as a list of defined values. [6] Gauge is commonly used today in reference to shotguns, though historically it was first used in muzzle-loading long guns such as muskets, then later on in breech-loading long guns including single-shot and ...

  7. Table of handgun and rifle cartridges - Wikipedia

    en.wikipedia.org/wiki/Table_of_handgun_and_rifle...

    This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).

  8. M60 machine gun - Wikipedia

    en.wikipedia.org/wiki/M60_machine_gun

    A camouflaged infantryman armed with an M60 machine gun. The M60 is a belt-fed machine gun that fires the 7.62×51mm NATO cartridge (similar to .308 Winchester), which is commonly used in larger rifles, such as the M14. It is generally used as a crew-served weapon and operated by a team of two or three individuals. The team consists of the ...
