Understanding the .308 Winchester Cartridge
Brief history of the .308 Winchester
The .308 Winchester cartridge, often simply referred to as .308, holds a prominent position in the world of firearms. Its widespread popularity stems from a unique combination of versatility, accuracy, and stopping power, making it a favored choice among hunters, target shooters, and even in some military and law enforcement applications. This article will delve into the fascinating world of guns that shoot .308, exploring the various types of firearms chambered for this potent round, and examine their specific features, benefits, and potential drawbacks. We’ll consider everything from bolt-action rifles ideal for long-range hunting to semi-automatic platforms favored for their rapid-fire capabilities.
Ballistics and performance characteristics of .308
The .308 Winchester has a rich history, closely intertwined with its military counterpart, the 7.62x51mm NATO cartridge. Born from a desire to create a short-action cartridge capable of delivering the same performance as the larger .30-06 Springfield, the .308 Winchester was introduced in 1952 by Winchester. It quickly gained traction in the civilian market, offering improved accuracy and shorter action lengths compared to the older cartridge. The development of the .308 Winchester mirrored the concurrent efforts within NATO to standardize the 7.62x51mm NATO, a military round designed for enhanced performance. While the two cartridges share very similar dimensions and can generally be fired interchangeably in modern firearms designed for either, there are subtle differences in chamber specifications and pressure tolerances that firearm owners should understand.
Popularity and widespread use of .308
The .308 Winchester shines in terms of ballistics. It excels at delivering excellent external ballistics with a relatively flat trajectory and significant retained energy at extended ranges. Available in a variety of bullet weights and designs, ranging from lighter bullets optimized for fast expansion to heavier bullets that maintain momentum and penetration, the .308 can be tailored to a wide variety of applications. Common bullet weights include those in the 150-grain to 180-grain range, often used for hunting medium to large game. Lighter bullets can be used in target shooting to minimize recoil and maximize trajectory flatness. The cartridge is celebrated for its capability to maintain effective impact over distance with suitable ballistic coefficients.
Firearms Chambered in .308 Winchester
The .308 Winchester’s enduring popularity speaks to its utility and value. The cartridge provides enough energy to take down a variety of big game animals, a factor that makes it indispensable for hunters across North America and around the world. Its accuracy and manageable recoil make it suitable for target shooting at various distances, and its widespread availability, with ammunition and firearms being readily available across the market, contribute to its appeal. The .308 Winchester is often cited as an excellent choice for those seeking a balance of power, range, and versatility in a single platform.
Bolt-Action Rifles
A diverse range of firearms have been designed to chamber the .308 Winchester. Each platform offers unique advantages and cater to specific needs and preferences, and all are well represented among the ranks of guns that shoot .308.
Description of the bolt-action mechanism
The bolt-action rifle, a cornerstone of firearm design, provides a robust, reliable, and inherently accurate platform for the .308 Winchester. The bolt-action mechanism involves a manually operated bolt that locks the cartridge securely in the chamber, creating a tight seal that contains the high pressure produced during firing. This mechanism is typically operated by a forward and rearward motion of the bolt, which loads, fires, and extracts spent casings. The solid lockup often leads to inherent accuracy and precise control of the cartridge at the moment of firing.
Popular bolt-action rifle models chambered in .308
Many renowned bolt-action rifles are chambered in .308 Winchester. The Remington 700 is a legendary platform, prized for its accuracy, durability, and aftermarket support. The Savage 10/110 series offers exceptional value, often providing excellent accuracy at a lower price point. Rifles from manufacturers like Tikka, known for their smooth bolt operation and build quality, are also chambered in .308. These bolt-action rifles represent the gold standard for precise, deliberate shooting.
Pros and cons of bolt-action .308 rifles
Bolt-action .308 rifles are known for their exceptional accuracy, which is a natural result of the design. The manually operated action also contributes to simplicity and reliability, with fewer moving parts. The slower rate of fire may not be suitable for all situations, such as rapid engagements in a tactical environment. The single-shot nature of the bolt-action, requiring manual cycling of the bolt after each shot, may also make it less desirable for some forms of hunting, such as those that involve multiple opportunities to fire, and situations where multiple shots might be necessary to dispatch game.
Best uses and scenarios for bolt-action rifles
These rifles perform well for applications where precision is paramount: long-range hunting, target shooting, and tactical marksmanship. The bolt-action is a favorite among those that value each shot, taking their time, and achieving maximum accuracy.
Semi-Automatic Rifles
Semi-automatic rifles utilize the expanding gases created during firing to cycle the action automatically, allowing for rapid follow-up shots. These are the rifles for which rapid engagement is essential, offering both firepower and the potential for faster follow-up shots, due to the automated action.
Description of the semi-automatic operating system
Several notable semi-automatic rifle platforms are available in .308 Winchester. AR-10-style rifles, based on the AR-15 design, but scaled up to accommodate the larger .308 cartridge, are popular. These are often highly customizable with various rails and accessories, with manufacturers like Aero Precision and Palmetto State Armory producing affordable yet reliable models. The FN SCAR 17 is another high-performance choice, known for its modularity and durability. The Springfield Armory M1A, a civilian variant of the M14 rifle, offers a classic design with a proven track record.
Popular semi-automatic rifle models chambered in .308
Semi-automatic .308 rifles offer significant advantages, including high rates of fire and enhanced maneuverability. They also present some drawbacks such as potential accuracy degradation over long-range shooting and a propensity for increased weight. They are sometimes more complex to maintain and are also typically more expensive than their bolt-action counterparts.
Pros and cons of semi-automatic .308 rifles
These rifles excel in scenarios that demand rapid engagement and immediate follow-up shots. Tactical applications, where quick and accurate follow-up shots are essential, and hunting situations where multiple shots might be necessary.
Best uses and scenarios for semi-automatic rifles
For those seeking to achieve extreme accuracy at extended ranges, specialized precision rifles chambered in .308 Winchester are an exceptional choice. These rifles are designed with features optimized for pinpoint accuracy.
Precision/Long-Range Rifles

Many high-end bolt-action models incorporate features specifically designed for long-range shooting, with the addition of such features as heavier barrels, adjustable stocks, and match-grade triggers.
Characteristics of rifles designed for long-range shooting
Precision rifles are distinguished by their heavy, free-floated barrels, designed to minimize barrel harmonics and reduce vibrations during firing. Adjustable stocks allow shooters to tailor the rifle to their body, ensuring consistent cheek weld and optimal scope alignment. High-quality scopes and precision mounts are crucial for long-range targeting. The rifle also offers specialized features, such as enhanced triggers to assist with minimal trigger pull and precise shooting.
