The gauge (in American English or more commonly referred to as bore in British English) of a firearm is a unit of measurement used to express the inner diameter (bore diameter) and other necessary parameters to define in general a smoothbore barrel (compare to caliber, which defines a barrel with rifling and its cartridge).

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.
The Spartan 310 has a walnut stock and fore-end, the shooter can select automatic ejectors or extractors, and a ventilated barrel rib. It uses screw-in SPR choke tubes.By default, the bottom barrel fires first, but the shooter can select the top barrel to fire first by pushing the trigger blade forward when the gun is loaded and closed.

The original patent filed by Hermann Gerlich in 1932 [6]. The squeeze bore concept was first patented by German inventor Carl Puff in 1903 [7] [8], even though the general principle was known already in 19th century and later applied in lighter fashion on Armstrong guns, on which only the muzzle yet not the barrel itself was of slightly smaller diameter (to cast off the sealing leather-bag ...
A third gauge, the "Field" gauge (slightly longer than "no-go"), is used in the field to indicate the absolute maximum safe headspace. This gauge is used because, over time, the bolt and receiver will wear, the bolt and lugs compress, and the receiver may stretch, all causing the headspace to gradually increase from the factory specifications ...
An intermediate cartridge is a rifle/carbine cartridge that has significantly greater power than a pistol cartridge but still has a reduced muzzle energy compared to fully powered cartridges (such as the .303 British, 7.62×54mmR, 7.65×53mm Mauser, 7.92×57mm Mauser, 7.7×58mm Arisaka, .30-06 Springfield, or 7.62×51mm NATO), and therefore is ...
The sabot component in projectile design is the relatively thin, tough and deformable seal known as a driving band or obturation ring needed to trap propellant gases behind a projectile, and also keep the projectile centered in the barrel, when the outer shell of the projectile is only slightly smaller in diameter than the caliber of the barrel ...
