Understanding the AR-15 Cartridge
The AR-15 is a popular firearm among enthusiasts and professionals alike. Its versatility and reliability make it a favorite for various applications, from hunting to tactical operations. One of the key factors that contribute to its popularity is the wide range of cartridges available for it. But what is the most powerful AR-15 cartridge? Let’s delve into the details to find out.
Cartridge Power: What Does It Mean?
Cartridge power refers to the energy released by a bullet when it is fired from a firearm. This energy is measured in foot-pounds of energy (ft-lbs) and is a crucial factor in determining the effectiveness of a cartridge. A higher ft-lbs value generally means more energy is transferred to the target, resulting in better penetration and stopping power.
