The Top Contenders: The Most Common Rifle Ammo
7.62x39mm
One of the truly ubiquitous rounds, a cartridge found across countless battlefields and shooting ranges, is the 7.62x39mm. This intermediate cartridge was a key innovation of the Soviet Union, developed during the Second World War and refined for mass production. It was originally designed for the SKS carbine and later the legendary AK-47 assault rifle. The Soviet Union saw the need for a round that offered greater range and stopping power than pistol-caliber submachine guns but still was controllable in full-auto fire. The 7.62x39mm was the answer.
The impact of the 7.62x39mm extends far beyond its Soviet origins. The AK-47 and its many variants were adopted by numerous countries and revolutionary movements, and the cartridge quickly became a symbol of the Cold War era and beyond. Today, it is still a stalwart of many militaries around the world, especially in former Soviet bloc nations, throughout Asia, Africa, and the Middle East. The cartridge is affordable to produce and delivers substantial stopping power at short to medium ranges, which, coupled with the AK-47’s legendary reliability, makes it ideal for use in harsh environments. This cartridge is used in a variety of firearms beyond the AK-47, including the SKS and many modern sporting rifles.
In the civilian market, the 7.62x39mm remains popular, providing a cost-effective option for hunting and recreational shooting. Its inherent simplicity and robust design make it a favorite among those seeking a rugged, reliable rifle.
5.56x45mm NATO / .223 Remington
Another cartridge that arguably contests for the top spot is the 5.56x45mm NATO, sometimes labeled and easily confused with the .223 Remington. Though the 5.56x45mm NATO and the .223 Remington are often used in the same platforms, they are technically different, but are often able to substitute one for the other. Developed in the United States, this round was initially conceived as a lighter, faster alternative to larger rifle cartridges. Its genesis traces back to the late 1950s, where the U.S. Army sought to replace the heavy and often difficult-to-control 7.62x51mm NATO in the M14 rifle. The intent was to give the individual soldier a greater capacity to carry more ammunition, while still delivering adequate lethal potential.
The 5.56x45mm NATO saw its initial widespread military use in the M16 rifle. This rifle was initially plagued with issues in the field, but the cartridge and platform were eventually refined and widely adopted. The round quickly became a standard across NATO forces, and subsequently, it spread throughout the world. Its success lies in its relatively flat trajectory, the high rate of fire achievable with the AR-15 platform, and the low recoil, allowing for accurate shooting. The 5.56x45mm NATO is now the standard rifle cartridge for a vast array of military and law enforcement agencies, including those in the United States, the United Kingdom, Canada, and many others. The cartridge has proven itself effective in combat situations, giving soldiers a high volume of fire at a manageable weight and recoil profile. The cartridge, with its corresponding platforms, is used in diverse environments and a multitude of climates.
The civilian sector mirrors the military’s embrace of the 5.56x45mm NATO, with AR-15-style rifles being extremely popular. Its relative affordability, the plethora of available accessories, and versatility make it suitable for target shooting, home defense, hunting, and competitive shooting. The standardization of the cartridge by numerous manufacturers and the widespread availability of ammunition solidify its place as one of the most common rifle ammo rounds globally.
7.62x51mm NATO / .308 Winchester
Though not as prevalent as the aforementioned rounds, the 7.62x51mm NATO, also known as .308 Winchester, still maintains a strong presence worldwide. This full-power rifle cartridge was developed in the 1950s and became the standard NATO battle cartridge for many years. The .308 Winchester, a civilian version of the 7.62x51mm NATO, gained similar popularity due to its effectiveness, range, and stopping power.
The 7.62x51mm NATO has a rich history and is utilized in various military weapons, including the FN FAL, the M14, and a host of machine guns and sniper rifles. The .308 Winchester is commonly used in bolt-action rifles, semi-automatic rifles, and various hunting platforms. The round boasts impressive performance, offering accuracy and stopping power at longer ranges than the 5.56x45mm NATO. This made the 7.62x51mm NATO a favorite for both military and civilian snipers.
While the 7.62x51mm NATO is increasingly being replaced by smaller calibers in some military applications, it remains a vital cartridge in many armies and is still a mainstay for military snipers, marksmen, and support weapons. The civilian market also embraces the .308 Winchester for hunting big game and recreational shooting, appreciating its versatility and effectiveness on a wider range of targets. The availability of affordable ammunition and the variety of firearms chambered in this caliber ensure the enduring popularity of the 7.62x51mm NATO/.308 Winchester.
.22 Long Rifle
When discussing common rifle ammo, it is impossible to overlook the .22 Long Rifle. This rimfire cartridge enjoys a ubiquitous presence across the globe. Its development dates back to the late 19th century, it is known for its low cost, low recoil, and inherent accuracy.
The .22 Long Rifle is found in a vast array of rifles, pistols, and even some submachine guns. Its popularity stems from its affordability, making it ideal for plinking, training, and recreational shooting. The .22 Long Rifle is also used for small game hunting and competitive shooting sports. The widespread production and easy availability of ammunition, coupled with the low cost of firearms chambered in this caliber, have solidified its position as a global favorite.
The low recoil and noise level of .22 Long Rifle make it a great choice for novice shooters and a favorite for people of all ages. From informal target practice to formal competitions, the .22 Long Rifle offers a user-friendly experience, making it a cornerstone of the shooting sports world.
Factors Influencing Ammunition Popularity
Several factors converge to determine which rounds become the most common rifle ammo in the world. Military adoption, the cornerstone of standardization, provides an immense boost to a cartridge’s popularity. When a major military power or alliance adopts a specific caliber, it immediately influences production, distribution, and civilian firearm designs. This ripple effect can make the caliber more accessible, cheaper, and reliable.
The availability and cost of ammunition are also crucial. The less expensive a cartridge is to produce, the more likely it will be widely adopted and used. Cost is also influenced by the ease of manufacturing, the materials involved, and the economies of scale achieved through mass production. A balance must be struck between affordability, performance, and the availability of the components necessary to produce the round.
The design and manufacturing of firearms also play a critical role. If a popular rifle platform is chambered for a specific round, that round is almost guaranteed to become more prevalent. A symbiotic relationship exists between firearm production and ammunition commonality. For instance, the AR-15’s design has fueled the popularity of the 5.56x45mm NATO. The AK-47’s global presence has made the 7.62x39mm a global standard.
Legislation and regulations also influence the landscape of ammunition. Gun control laws, both within individual countries and internationally, can impact ammunition availability, prices, and the types of rounds that are legal to own. Restrictions on certain calibers or bullet types can alter consumer preferences and affect market dynamics.
Trends and Future Considerations
The world of ammunition is constantly evolving. Technological advancements are leading to more efficient and more effective rounds. Some of the future trends in ammunition include the use of new materials, such as lighter alloys and polymer-based casings, the optimization of bullet designs to improve ballistics and terminal performance, and developments in propellant technology to enhance energy transfer and reduce fouling.
Geopolitical changes, with shifts in alliances and conflicts, could have a profound impact on the landscape of ammunition. If one nation or alliance adopts a new caliber, that could cause an increase in its overall usage and could potentially displace existing standards. Also, evolving military doctrines and civilian needs will continue to shape the demand for specific rounds. The trend toward smaller, more efficient firearms, for example, may lead to an increase in the popularity of certain intermediate cartridges.
