.308 Norma Mag Ammo: In Depth
The .308 Norma Magnum, also known as the 7.62x65mm Norma, is a powerful rifle cartridge designed for long-range shooting and big game hunting. Developed by Norma Precision AB in Sweden, this cartridge offers exceptional ballistic performance, flat trajectory, and high energy retention at extended ranges. The .308 Norma Mag is known for its versatility in handling various bullet weights and its ability to take down large game animals efficiently.
History and Development
The .308 Norma Magnum was introduced in 1960 by Nils Kvale at Norma Precision AB. It was designed to bridge the gap between the .308 Winchester and the .300 Winchester Magnum, offering improved ballistic performance over the former while being more manageable than the latter. The cartridge was based on a necked-down .338 Winchester Magnum case, providing ample case capacity for high velocity loads.
Initially, the .308 Norma Mag gained popularity among European hunters and long-range shooters. Its ability to handle heavy bullets with high sectional density made it particularly effective for taking large game at extended ranges. The cartridge\'s design allowed for excellent accuracy potential, making it a favorite among precision rifle enthusiasts.
Throughout the 1960s and 1970s, the .308 Norma Mag saw increased adoption in North America, particularly among hunters pursuing elk, moose, and other large game. Its flat trajectory and high energy retention at long distances made it an excellent choice for open country hunting.
While never achieving the widespread popularity of some other magnum cartridges, the .308 Norma Mag has maintained a dedicated following among long-range shooters and hunters who appreciate its ballistic performance and versatility. Modern advancements in bullet design and propellants have further enhanced the cartridge\'s capabilities, ensuring its continued relevance in the 21st century.
Ballistic Performance
The .308 Norma Mag is capable of pushing 180-grain bullets to velocities exceeding 3,000 fps from a 24-inch barrel. This high velocity, combined with the excellent ballistic coefficients of modern bullets, results in a very flat trajectory and high retained energy at long ranges. At 500 yards, a typical 180-grain load still retains over 2,000 ft-lbs of energy, making it effective for large game at extended distances.
The cartridge\'s ability to handle heavy bullets with high sectional density contributes to its excellent penetration and terminal performance on large game. Bullets weighing from 150 to 200 grains are commonly used, with the heavier projectiles being particularly favored for their wind-bucking ability and energy retention at long range.

.308 Norma Magnum Performance
The .308 Norma Magnum offers excellent ballistic performance, making it suitable for long-range shooting and big game hunting. Here\'s a breakdown of its key performance characteristics:
| Characteristic | Performance |
|---|---|
| Velocity | 3,000-3,200 fps (180-grain bullets) From a 24-inch barrel |
| Energy | 3,600-3,800 ft-lbs at the muzzle (180-grain bullets) Provides excellent terminal performance on large game |
| Trajectory | Approximately 21 inches of drop at 500 yards (180-grain bullet, 200-yard zero) Flat trajectory suitable for long-range shooting |
| Effective Range | 1,000 yards for target shooting, 600 yards for ethical hunting Depends on shooter skill and specific load |
| Recoil | Moderate to heavy, approximately 25-30 ft-lbs in a typical rifle Manageable for experienced shooters, may be challenging for new shooters |
