A cartridge, [1] [2] also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (smokeless powder, black powder substitute, or black powder) and an ignition device within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of ...
The term bullet is from Early French, originating as the diminutive of the word boulle (boullet), which means "small ball". [3] Bullets are available singly (as in muzzle-loading and cap and ball firearms) [4] but are more often packaged with propellant as a cartridge ("round" of ammunition) consisting of the bullet (i.e., the projectile), [5 ...
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 ...

The hollow point made the express bullet lighter, faster, and disabled thin-skinned animals more quickly than a solid bullet, at the expense of penetration power and bullet sturdiness. [ 1 ] The term express was first applied to hunting rifles and ammunition beginning in the mid-19th century, to indicate a rifle or ammunition capable of higher ...
A full metal jacket (FMJ) bullet is a small-arms projectile consisting of a soft core (often lead) encased in an outer shell ("jacket") of harder metal, such as gilding metal, cupronickel, or, less commonly, a steel alloy. A bullet jacket usually allows higher muzzle velocities than bare lead without depositing significant amounts of metal in ...

Expanding bullets are designed to expand on impact, sometimes as much as twice the diameter. [3] This will slow the bullet down and more of its kinetic energy will be transferred to the target, creating a larger wound channel. For this reason, expanding bullets are often used in hunting because their stopping power increases the chance of a ...
