This has got to be one of my favorite calibers. Seriously, if you are prepping for the Bugaboo this is your match.
The .308 Winchester is a rimless, bottle-necked, rifle cartridge and is the commercial cartridge from which the 7.62×51mm NATO round was derived. The .308 Winchester was introduced in 1952, two years prior to the NATO adoption of the 7.62×51mm NATO T65. Winchester branded the cartridge and introduced it to the commercial hunting market as the .308 Winchester.
