The .308 Norma Magnum is a rifle cartridge that was introduced by the Swedish ammunition manufacturer Norma in the early 1960s. It is based on the .300 H&H Magnum case, which has been shortened and modified to optimize performance in standard-length rifle actions. The .308 Norma Magnum is known for its high velocity and flat trajectory, making it suitable for long-range shooting. It is particularly favored for big game hunting, including species such as deer, elk, and moose, thanks to its powerful ballistics and reliable accuracy.
The cartridge typically fires a bullet in the range of 150 to 200 grains, achieving muzzle velocities between 3,000 and 3,200 feet per second, depending on the load. These characteristics provide excellent penetration and energy transfer, which are crucial for effective hunting.
Although it offers impressive performance, the .308 Norma Magnum is not as widely adopted as other magnum cartridges like the .300 Winchester Magnum. However, it retains a dedicated following among hunters and long-range shooters for its combination of power and precision.
Overall, the .308 Norma Magnum is a versatile and potent choice for those requiring strong performance in hunting and target applications.
