There are literally hundreds of types of rifle ammo for sale on the market today, some of which are much more popular than others. However, there are two main categories that each rifle cartridge falls under – rimfire and centerfire.
A rimfire cartridge is a firearm cartridge in which the firing pin strikes the rim of the cartridge base. The rim of a rimfire cartridge is a wide and long percussion cap that holds priming compound, and the cartridge case contains the gunpowder and the bullet. Rimfire cartridges are some of the only rifle ammo for sale that can’t be reloaded after the first firing, since the head is reshaped by firing pin impact. Rimfire ammo can only be utilized in low pressure calibers, since they require a thin case for the primer to be ignited by the firing pin. Therefore, rimfires are generally .22 caliber or less.
A centerfire cartridge is a type of rifle ammo for sale in which the primer is contained in the center of the cartridge case head. The primer in a centerfire cartridge is separate and therefore replaceable, unlike rimfire cartridges. Thus, the rimfire cartridge is only used in the smallest cartridge sizes, but almost all modern rifle ammunition on sale is centerfire.
The obvious advantage of a centerfire cartridge is that they can be reused. Centerfire cartridges are also capable of much higher powered loads than the rimfire cartridges. Although centerfire cartridges are slightly more expensive, they are the perfect choice for hunting big game.
