EPVAT is an abbreviation for "Electronic Pressure, Velocity and Action Time" (French "Pression électronique, vitesse et durée d’action"). Action Time here means the (short amount of) time required between the ignition of the primer and the projectile leaving the barrel. This is a comprehensive procedure for testing ammunition using state-of ...
The 5.56×45mm NATO standard SS109/M855 cartridge was designed for maximum performance when fired from a 508 mm (20.0 in) long barrel, as was the original 5.56 mm M193 cartridge. Experiments with longer length barrels up to 610 mm (24.0 in) resulted in no improvement or a decrease in muzzle velocities for the SS109/M855 cartridge.
NATO defines 5.56mm, 7.62mm, 9mm, and 12.7mm using the NATO EPVAT test methods, which includes pressure testing. Unlike the civilian testing methods NATO EPVAT testing procedures for the "NATO rifle chamberings" require the pressure sensor or transducer to be mounted ahead of the case mouth.

The 5.45×39mm cartridge is a rimless bottlenecked intermediate cartridge.It was introduced into service in 1974 by the Soviet Union for use with the new AK-74.The 5.45×39mm gradually supplemented and then largely replaced the 7.62×39mm cartridge in Soviet and Warsaw Pact service as the primary military service rifle cartridge.
The table below gives a list of firearms that can fire the 5.56×45mm NATO cartridge, first developed and used in the late 1970s for the M16 rifle, which to date, is the most widely produced weapon in this caliber. [1] Not all countries that use weapons chambered in this caliber are in NATO. This table is sortable for every column.
A medieval view of fish processing, by Peter Brueghel the Elder (1556). There is evidence humans have been processing fish since the early Holocene. For example, fishbones (c. 8140–7550 BP, uncalibrated) at Atlit-Yam, a submerged Neolithic site off Israel, have been analysed. What emerged was a picture of "a pile of fish gutted and processed ...
