The .338 Federal is a rifle cartridge based on the .308 Winchester case necked up to .33 caliber. It was created by Federal Cartridge and Sako in 2006 and intended as a big game cartridge with reasonable recoil for lightweight rifles.
In terms of performance, the .338 Federal compares favorably with cartridges that have similar capacities and purposes. It has less recoil yet similar muzzle velocity and energy compared to the 7mm Remington Magnum in bullets of the same weight while having greater energy than the .30-06 Springfield. The .300 Winchester Magnum is also a worthwhile comparison despite the .300's considerably higher recoil. Also included in the table below is the older .358 Winchester, another cartridge based on the .308.
