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.
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. It shares dimensions with the .32 ...
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.
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.

The surgeons used to see .22-caliber bullets from little handguns, Saturday night specials, whereas now they see .40-caliber and 9 mm bullets. Charles said they get the occasional victim of a long gun, such as an AR-15 or an AK-47, “but what’s remarkable is how common handguns are.”
Note: Use of this table for estimating bullet masses for historical large-bore rifles is limited, as this table assumes the use of round ball, rather than conical bullets; for example, a typical 4-bore rifle from circa 1880 used a 2,000-grain (4.57 oz; 129.60 g) bullet, or sometimes slightly heavier, rather than using a 4-ounce (110 g) round ...
