Ammunition can be an intimidating subject if you are not knowledgeable in the firearm department. Selecting the right ammunition for your firearms whether for hunting or personal defense is an important decision. Having the proper ammunition is necessary to keeping your firearm safe while having optimal performance. This topic can be overwhelming and confusing but we have simplified it for you.
Ammunition is general indicated in a measurement. The United States commercial market uses a U.S standard measurement while most of the world uses a metric system. The measurements in metric are almost always a “diameter to length” ratio. For example: 5.56x45mm is 5.56mm wide and 45mm long. Shotshells are measured in “gauge”, with a lower number being a larger in diameter. For Example: A typical 12 gauge shell is 70mm long, which works out to be 2½”.
A cartridge is made up of four components: case, primer, powder/propellant, and projectile.
Bullets come in a variety of types that are used for different purposes. Each bullet is commonly referred to by it’s suffixed acronym making The different types of bullets are listed and pictured below.
Soft Point (SP): The tip of this bullet is exposed lead.
Armor Piercing (AP): The core is composed of alloy instead of lead.
Boat Tail (BT): The rear end of the cartridge is tapered to stabilize the projectile in flight.
Boat Tail Hollow Point (BTHP): This is a combination of the boat tail and hollow point features.
