While modern firearms are generally referred to by the name of the cartridge the gun is chambered for, they are still categorized together based on bore diameter. [citation needed] For example, a firearm might be described as a "30 caliber rifle", which could accommodate any of a wide range of cartridges using a roughly 0.30 inches (7.6 mm) projectile; or as a "22 rimfire", referring to any ...
Some of the revolver cartridges in this caliber are: 7.62×38mmR is used only in the Nagant M1895 revolver..32 Long Colt – originally chambered for small-frame Colt revolvers and the Marlin model 1892 rifle, this cartridge uses a heeled bullet with a case the same diameter as the major diameter of the bullet.

Bullets are often tapered, making them more aerodynamic. Bullet size is expressed by weight and diameter (referred to as "caliber") in both imperial and metric measurement systems. [1] Bullets do not normally contain explosives [2] but strike or damage the intended target by transferring kinetic energy upon impact and penetration.
The .22 CB Cap (Conical Bullet Cap), also known as the 6mm Flobert, is a more powerful version of the .22 BB Cap rimfire metallic cartridge, which was invented by Louis-Nicolas Flobert in 1845. The .22 BB Cap and .22 CB Cap are interchangeable and are relatively quiet, low velocity cartridges, designed for indoor target shooting.
The .30-06 (or "caliber .30") cartridge was adopted in 1940 during the beginnings of the Lend-Lease program in anticipation of using American weapons in front-line service. The British used American-made ammunition during the war, which was designated as cartridge S.A, .30 to avoid confusing it with their own .303 British service round. It was ...
Many shooters wonder why a .38 caliber firearm actually shoots bullets of .357 in (9.1 mm) diameter, and a .44 caliber firearm shoots bullets of .429 in (10.9 mm) diameter. In both of these cases, the name of the caliber derives from older heeled-bullet designs, and the name was kept even when the bullet was shrunk to fit inside the case.
Only small-caliber rimfire cartridges and centerfire cartridges have survived into the modern day. Military and commercial producers continue to pursue the goal of caseless ammunition. Some artillery ammunition uses the same cartridge concept as found in small arms. In other cases, the artillery shell is separate from the propellant charge.
The new cartridge, the .360 Buckhammer, or .360 BHMR for short, is based on a .30-30 Winchester case that has been blown out to get rid of the shoulder and necked up to accommodate .358-caliber bullets (the same bullets used in the .35 Remington).
