.338 Federal: A Comprehensive Overview

The .338 Federal is a rifle cartridge developed by Federal Premium Ammunition in collaboration with Sako. It was introduced in 2006 as a magnum-class cartridge based on the .308 Winchester case necked up to .338 caliber. The .338 Federal offers improved ballistics over the .308 Winchester while maintaining moderate recoil, making it an excellent choice for medium to large game hunting at medium ranges.

Development and Characteristics

The .338 Federal was designed to bridge the gap between the .308 Winchester and larger magnum cartridges. It uses a .308 Winchester case necked up to accept .338 caliber bullets, typically weighing between 180 and 210 grains. This combination results in a cartridge that delivers magnum-level performance from a standard-length action, offering hunters increased power without the need for a larger, heavier rifle.

One of the key advantages of the .338 Federal is its efficiency. The cartridge achieves high velocities with moderate powder charges, resulting in less recoil than larger magnum cartridges while still delivering excellent terminal performance on medium to large game. This makes it particularly suitable for hunters who want magnum-class performance in a more manageable package.

Applications and Performance

The .338 Federal excels in hunting scenarios involving medium to large game at moderate ranges. It is particularly effective on animals such as elk, moose, and bear. The cartridge's combination of bullet weight and velocity results in high kinetic energy transfer and deep penetration, ensuring clean, ethical kills on large animals.

In terms of ballistics, the .338 Federal typically propels a 200-grain bullet at velocities around 2,700 fps, generating over 3,200 ft-lbs of muzzle energy. This performance surpasses the .308 Winchester while remaining more manageable than larger magnum cartridges like the .338 Winchester Magnum. The cartridge maintains supersonic velocities beyond 500 yards, making it effective for long-range shooting as well.
