The debate between the .308 Winchester and the 7.62x51mm NATO has been a long-standing discussion among rifle enthusiasts and hunters. Both cartridges are widely used and have their own set of advantages and considerations. In this blog post, we will delve into the details, compare their performance, and help you decide which one might be the better choice for your specific needs.
Understanding the .308 Winchester and 7.62x51mm NATO
The .308 Winchester, also known as the 7.62x51mm, is a popular centerfire rifle cartridge that has gained immense popularity among hunters and target shooters. It was introduced by Winchester Repeating Arms Company in 1952 and quickly became a go-to choice for many due to its versatility and performance.
On the other hand, the 7.62x51mm NATO cartridge was developed primarily for military use. It was adopted by NATO (North Atlantic Treaty Organization) as a standard rifle cartridge in 1954. While it shares the same bullet diameter and case length as the .308 Winchester, there are some subtle differences between the two.
Cartridge Specifications
Let's take a closer look at the specifications of these two cartridges to understand their similarities and differences.
Case Dimensions
- .308 Winchester: The .308 Winchester cartridge has a case length of 51mm and a rimless design. It is known for its reliable performance and is widely used in bolt-action rifles.
- 7.62x51mm NATO: The 7.62x51mm NATO cartridge also has a case length of 51mm, but it features a semi-rimmed design. This cartridge is optimized for use in military-style rifles, such as the M14 and the FN FAL.
Bullet Diameter
Both the .308 Winchester and 7.62x51mm NATO cartridges utilize a bullet diameter of 0.308 inches (7.82mm). This bullet size is commonly used in various hunting and target shooting applications.
Powder Capacity
The powder capacity of a cartridge refers to the amount of propellant it can hold. The .308 Winchester typically has a slightly higher powder capacity compared to the 7.62x51mm NATO. This difference allows the .308 Winchester to achieve slightly higher velocities with the same bullet weight.
