Performance Comparison

While the 7.62 NATO and .308 Win share many similarities, there are some performance differences worth noting:

Velocity and Energy

The 7.62 NATO typically has a higher muzzle velocity and delivers more energy downrange compared to the .308 Win. This makes it more effective for long-range shooting and penetrating heavier targets.

Recoil

Due to its higher velocity and energy, the 7.62 NATO produces more recoil than the .308 Win. This can be a consideration for shooters, especially those who prefer lighter-recoiling firearms.

Availability and Cost

Both cartridges are widely available, but the 7.62 NATO is more commonly associated with military and law enforcement, while the .308 Win is more prevalent in the civilian market. As a result, the .308 Win often has a wider variety of ammunition options and can be more cost-effective for recreational shooters.

Choosing the Right Cartridge

Hunting

Hunters often prefer the .308 Win for its versatility and manageable recoil. It offers excellent performance for a wide range of game, making it a popular choice for deer, elk, and other medium to large game hunting.

Target Shooting

Both cartridges are suitable for target shooting, but the .308 Win's availability and cost-effectiveness make it a popular choice for recreational shooters. Its accuracy and flat trajectory make it ideal for long-range target practice.

Compatibility and Rifle Platforms

An important consideration when choosing between the 7.62 NATO and .308 Win is rifle compatibility. Many modern rifles are chambered for both cartridges, but there are some key differences to be aware of:

Barrel Length

The 7.62 NATO is often used in shorter-barreled rifles, while the .308 Win performs best with longer barrels. This is due to the higher velocity and pressure requirements of the 7.62 NATO, which can be better managed with a longer barrel.

Action Length

Magazines

Magazines designed for the 7.62 NATO are often longer to accommodate the longer case. This can impact the overall length and capacity of the rifle. The .308 Win, with its shorter case, allows for more compact magazines and rifles.

Ammunition Availability and Cost

Ammunition availability and cost are important factors to consider when choosing between the 7.62 NATO and .308 Win. The .308 Win, being a civilian cartridge, often has a wider variety of ammunition options available, including various bullet weights, types, and loads. This can be beneficial for hunters and target shooters who want to fine-tune their ammunition for specific applications.

In terms of cost, the .308 Win is generally more affordable than the 7.62 NATO. This is due to the civilian market demand and the wider availability of .308 Win ammunition. The 7.62 NATO, being a military cartridge, may have limited options and higher prices, especially for specialized loads.
