Caliber is one of the most important concepts in shooting. It refers to the internal diameter of a gun barrel or the diameter of the bullet. Understanding caliber helps you choose the right ammunition for your firearm.
Common Calibers:
– 9mm: Popular for self-defense and range use due to low recoil and wide availability.
– .45 ACP: Known for stopping power, often used in home defense.
– .223 Rem / 5.56 NATO: Common rifle caliber used in AR-15 platforms for target and tactical shooting.
– .308 Winchester: Ideal for hunting medium to large game, offering accuracy and knockdown power.
– .22LR: Great for beginners, small game hunting, and training thanks to low cost and minimal recoil.
Each caliber has unique characteristics that affect trajectory, recoil, penetration, and performance. Make sure your firearm is rated for the caliber you choose.
