The .308 Winchester has seen multiple uses including military sniper rifles, belted machine guns, and long-range competitions, and is even rated as one of the best hunting calibers by Outdoor Life. Calibers developed from the .308 include the .243 Winchester, 7mm-08 Remington, .260 Remington, and the .358 Federal. With relatively low recoil, it is the most popular short action, big game hunting caliber worldwide.Bear Creek Arsenal offers the .308 Winchester in its AR10 platform with common group sizes in the 1” to 1 ½” range. Game animals from groundhogs to black bears need to be on alert!
