Unlike the IZ-109 manually adjustable gas regulator system used on the Saiga-12, the gas system on the Vepr-12 is a clone of the IZ-433 unregulated fixed open port tappet system, allowing the Vepr-12 to cycle most commercially available 12-gauge loads, from 3.25 dram equivalent and up, without risking damage to the shotgun and without requiring ...
This measurement comes from the time when early cannons were designated in a similar manner—a "12 pounder" would be a cannon that fired a 12-pound (5.4 kg) cannonball; inversely, an individual "12-gauge" shot would in fact be a 1 ⁄ 12 pounder. Thus, a 10-gauge shotgun has a larger-diameter barrel than a 12-gauge shotgun, which has a larger ...
The brass cartridge cases contained three different types of loads: light at 12 drams, 14 drams at regular, and 16 drams of powder at heavy load. (Note: 1 dram = 27.34375 grains in the avoirdupois system, since 256 drams = 7000 grains = 1 pound of powder. Shotgun shells are still rated in terms of the same archaic dram measurements, relative to ...
Gauge was determined from the weight of a solid sphere of lead that will fit the bore of the firearm and is expressed as the multiplicative inverse of the sphere's weight as a fraction of a pound, e.g., a one-twelfth pound lead ball fits a 12-gauge bore. Therefore with a 12-gauge, it would take 12 balls of lead of the same size as the 12 gauge ...
Military use of combat shotguns through the 20th century has created a need for ammunition maximizing the combat effectiveness of such weapons within the limitations of international law. 12-gauge has been widely accepted as an appropriate bore diameter to provide an effective number of projectiles within an acceptable recoil.
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
Hitachi and NEC introduced 256 Mb DRAM memory chips manufactured with this process in 1993, followed by Matsushita, Mitsubishi Electric and Oki in 1994. [47] NEC's 1 Gb DRAM memory chip in 1995.

A teaspoonful has been considered equal to one fluid dram for medical prescriptions. [19] However, by 1876 the teaspoon had grown considerably larger than it was previously, measuring 80–85 minims. [20] As there are 60 minims in a fluid dram, [5]: C-5, C-7 using this equivalent for the dosage of medicine was no longer suitable. [20]
