Centerfire ammunition is used for rifles, shotguns, and handguns. In this type of ammunition, the primer is located in the center of the casing base. Rimfire ammunition has the primer contained in the rim of the ammunition casing. Rimfire ammunition is limited to low-pressure loads.
What is the barrel of a rifle called?
When shooting, a rifled bore imparts spin to the projectile about its longitudinal axis, which gyroscopically stabilizes the projectile’s flight attitude and trajectory after its exit from the barrel (i.e. the external ballistics). Any gun without riflings in the bore is called a smoothbore gun.

What is the most powerful rimfire rifle?
The most powerful rim fire cartridge in existence today is the . 17 WSM ( Winchester Super Magnum). It pushes a 20 grain bullet around 3000 fps with 400 foot pounds of energy at the muzzle. These results are a breakthrough in rim fire technology and drastically increase the capability of the cartridge class.
Which is better rimfire or centerfire pistols?
Due to the primer being set above the cartridge base, centerfire ammunition casings are not rendered useless after firing. This gives centerfire ammo a huge advantage over rimfire. Centerfire cartridges often carry heavier projectiles. This allows for a more accurate shot at longer distances.

Rifle barrels are often described as heavy (varmint/target), medium (sporter), or light. This refers to the thickness of the steel surrounding the bore.
What kind of hole does a gun barrel have?
All gun barrels have a cylindrical hole running completely through them, known as the bore, in which the bullet or shot swarm travels as it is accelerated. In rifles and handguns, the bore has spiral lands and grooves, which are called “rifling.”
