Bullet - online puzzles

A bullet is a component of firearm ammunition and is the projectile expelled from the firearm 's barrel. The term is from Middle French and originated as the diminutive of the word boulle (boullet), which means "small ball ". Bullets are made of a variety of materials such as copper, lead, steel, polymer, rubber and even wax. They are available either singly as in muzzleloading and cap and ball firearms, or as a component of paper cartridges and much more commonly metallic cartridges. Bullets are made in a large number of shapes and constructions depending on the intended applications, including specialized functions such as hunting, target shooting, training and combat.

Though the word "bullet" is often used incorrectly in colloquial language to refer to a round of ammunition, a bullet is not a round of ammo but rather a component of one. A round of ammunition is a combination package of the bullet, cartridge, propellant and primer. This use of the term "bullet" when round is intended often leads to confusion when the components of a cartridge are intended.

Bullet sizes are expressed by their weights and diameters (referred to as "calibers") in both imperial and metric measurement systems. For example: 55 grain.223 caliber bullets are of the same weight and caliber as 3.56 gram 5.56mm caliber bullets.
