Handguns are smaller-caliber weapons with shorter barrels, and are meant to be fired using one or both hands. As a general rule, long guns fire large-caliber rounds from long barrels and are meant to be fired from the shoulder. There are many kinds of guns in circulation today, but they can be divided into two categories: long guns, including rifles and shotguns, and handguns, including revolvers and pistols. “Snake rounds,” pistol rounds that fire a spread of small metal pellets, are useful for killing-you guessed it-dangerous snakes at a distance. Both are generally restricted to military use. Tracer bullets are designed to allow the shooter to see where his or her bullets are striking at night, and armor-piercing bullets can penetrate body armor and light steel armor. Hollow-point bullets have a cavity in the nose of the bullet that allows the lead to spread outward on impact, morphing the aerodynamic bullet into a deadly, high-velocity metallic flower, creating gaping wounds.

22 Long has a longer range, travels at a higher velocity, and is much more lethal because of the shape of the bullet and the use of more gunpowder.īullets also have different shapes or other features to take on different tasks. 223 round, just a tiny bit wider in diameter than. 22 Long round is meant for small game hunting and light target practice. Some are for smaller shooters more sensitive to recoil, others are for long-range shooting, while still others are for close-range self-defense. This is starting to sound complicated, but what you really need to know is that, generally, a single gun can only shoot a single kind of bullet.ĭifferent types of bullet calibers are meant to accomplish different tasks, and there are literally hundreds of bullet calibers. 22 Short round is primarily meant for pistols, while the. 357 Magnum revolver bullet will not fit in a Glock pistol chambered in. That said, a bullet’s diameter does not mean it will fit in every gun of that size, and there are many sub-varieties of ammunition.

Today’s firearms have magazines capable of holding up to 30 or more bullets, or more than one barrel, or can fire more than one bullet per pull of the trigger. This is a broad definition that covers everything from potato guns to fully automatic machine guns, but it provides the basic definition of what a gun is and how it works.Īdmittedly, the rapid evolution of guns makes it hard to look at them and see their basic components-a trigger, firing pin, and tubes. Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) defines a firearm as “any weapon (including a starter gun) which will or is designed to or may readily be converted to expel a projectile by the action of an explosive.” In other words: if you have a tube and a projectile, and the projectile is designed to fly out of the tube as the result of an explosion, you have a firearm. In order to better understand firearms, we’ve created this guide to how guns work, where we look at the weapon as a tool and study its history in addition to how different types function. I’ve built several of my own rifles, enjoy shooting and tinkering with other types of guns, and have handled almost every major gun type built in the last 500 years. This leads to increased gun violence and fear. Unfortunately, it seems as more time passes, gun literacy declines. Guns are a part of American life they’re woven into our history from the time matchlock muskets armed the earliest colonies, to the Colt revolvers and Winchester rifles of the Old West, to the Glock handgun of today.
