One of the newest members of the .308 Winchester family, the .338 Federal was introduced in 2006 by Federal and Sako. It is capable of achieving the same muzzle energy as some magnum calibers with less recoil. It also fits in standard length short action rifles and AR-10’s without sacrificing magazine capacity. It hits harder than the .308, and shoots flatter than the .358 Winchester, making it an excellent choice for a close to mid-range hunting caliber.
