History
The .308 Winchester cartridge was introduced in 1952 by Winchester. It was designed for hunting and target shooting, offering excellent accuracy and performance. On the other hand, the 7.62x51mm NATO cartridge was developed in the 1950s for military use. It is the standard round used by NATO forces and is known for its reliability and stopping power.
Dimensions
One of the key differences between the .308 and 7.62 cartridges is their dimensions. The .308 cartridge has a slightly shorter case length compared to the 7.62 cartridge. This can affect the overall performance and pressure levels of the rounds. Additionally, the .308 cartridge may have tighter tolerances, leading to better accuracy in some rifles.
Pressure Levels
Another important factor to consider when comparing the .308 and 7.62 cartridges is their pressure levels. The .308 cartridge is loaded to higher pressure levels compared to the 7.62 cartridge. This can result in increased velocity and energy, making the .308 a popular choice for long-range shooting. However, it is essential to ensure that your rifle can handle the higher pressure levels of the .308 cartridge.
Compatibility
One of the advantages of the 7.62 cartridge is its compatibility with a wide range of rifles. Many military surplus rifles are chambered in 7.62x51mm NATO, making it a popular choice for shooters looking for affordable ammunition.
