The United States boasts a diverse landscape of firearms, and with that diversity comes a wide array of calibers. Understanding the most common calibers is crucial for anyone interested in shooting sports, hunting, self-defense, or simply appreciating firearms history and culture. This guide delves into the most prevalent calibers in the USA, exploring their applications and popularity.
Top Tier: The Reigning Calibers
Several calibers consistently dominate the US firearms market, driven by a combination of historical significance, versatility, and widespread availability.
9mm Luger (9x19mm Parabellum): The King of Handguns
The 9mm Luger, often simply called 9mm, reigns supreme as the most popular handgun caliber in the US. Its widespread adoption stems from its effective balance of stopping power, manageable recoil, and relatively high capacity magazines. Law enforcement agencies at all levels utilize the 9mm, further solidifying its ubiquitous presence. Its affordability and wide availability of ammunition also contribute to its popularity among civilians for self-defense and recreational shooting.
.22 Long Rifle: The Versatile Workhorse
The diminutive .22 Long Rifle (.22 LR) holds a special place in American firearms culture. Its incredibly low recoil, inexpensive ammunition, and remarkable accuracy make it ideal for target practice, plinking, small game hunting, and even self-defense in close quarters (though its stopping power is significantly less than larger calibers). It's a staple for beginning shooters due to its ease of use and affordability. Its ubiquity is cemented by its use in countless firearms, from simple bolt-action rifles to semi-automatic pistols.
.45 ACP (Automatic Colt Pistol): The Heavyweight Contender
The .45 ACP holds a strong position, particularly among those seeking substantial stopping power. Its larger diameter and heavier bullet create significant recoil, but the resulting energy transfer is highly effective. Historically popularized by the US military, the .45 ACP remains a favored choice for self-defense and competition shooting. Despite the rise in popularity of 9mm, the .45 ACP's reputation for stopping power continues to ensure its place amongst the most common calibers.
5.56x45mm NATO (.223 Remington): The Assault Rifle Standard
In the realm of rifles, the 5.56x45mm NATO (.223 Remington) stands out as the dominant cartridge. Adopted by the US military (as the M16 and M4 carbines are chambered in 5.56 NATO), its widespread use has driven civilian demand. This caliber provides a good balance of accuracy, range, and manageable recoil for both target shooting and hunting smaller game. Its relatively light recoil makes it easier to handle than larger calibers like the .308 Winchester.
Other Notable Calibers
While the above calibers dominate the market, several others hold significant positions:
.223 Wylde: A Hybrid Solution
A blend of the .223 Remington and 5.56x45mm NATO, the .223 Wylde chamber allows the use of both cartridges. This enhanced versatility has made it popular among AR-15 owners.
.308 Winchester (7.62x51mm NATO): The Powerful Hunting Round
The .308 Winchester offers significantly greater power and range than the 5.56, making it a highly sought-after choice for hunting larger game. Its military counterpart, the 7.62x51mm NATO, further enhances its widespread adoption.
12 Gauge: The Shotgun King
For shotguns, the 12 gauge remains the undisputed king. Its versatility, availability, and power make it perfect for everything from hunting waterfowl to home defense.
Conclusion: Choosing the Right Caliber
