Bullet Weight: These will be measured in grains with 7.000 comprising a pound (a minuscule unit).Energy: The approximate power of each round.Velocity: The precise speed of the bullet in feet/sec.Let’s take a look at the definition and units of some of the factors that we’ll be considering when exploring the different caliber sizes. Are you going toe to toe with an extraterrestrial invasion? Probably you’ll want something a bit larger. Are you taking pot shots at squirrels in your backyard? For something like this, I usually prefer a smaller caliber as they are typically more accurate to this end. When it comes to cartridges, the shooter has a wide range of options to choose from. The cartridge comprises the other half of that equation and is key to the rifle shooting process. The rifle is but a part of the equation here. This means that you can faraway targets with unsurpassed accuracy.
Rifles and rifle cartridges can be fired at ranges that handguns were not designed to. Technically speaking, a bullet is only the metal projectile whereas the entirety of the round you fire is called a “cartridge.” This includes the casing, the powder and the primer.įor a more in-depth guide of ammo and bullets, check out our bullets guide. Some people might wonder why we don’t just call it “ bullet size,” but there’s a good reason for that. Rifle caliber means the size of the bullet’s diameter which can be measured in either inch or metric units ( mm or millimeter).
