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]
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 ...
The six most common shotgun gauges, in descending order of size, are the 10 gauge, 12 gauge, 16 gauge, 20 gauge, 28 gauge, and .410 bore. [7] By far the most popular is the 12 gauge, [7] particularly in the United States. [8] The 20-gauge shotgun is the next most popular size [citation needed], and is popular for upland game hunting. The next ...
A caliber conversion device is a device which can be used to non-permanently alter a firearm to allow it to fire a different cartridge than the one it was originally designed to fire. The different cartridge must be smaller in some dimensions than the original design cartridge, and since smaller cartridges are usually cheaper, the device allows ...
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 ...

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. Early 12-gauge ...
United States customary units form a system of measurement units commonly used in the United States and most U.S. territories [1] since being standardized and adopted in 1832. [2] The United States customary system developed from English units that were in use in the British Empire before the U.S. became an independent country.
