0.308

.308. Originally a military cartridge (7.62mm NATO), the .308 is so accurate that it was once used in benchrest competition and is a favorite with military and police snipers. If you’re interested in gilt-edged accuracy, this is the one. It comes in a wide variety of loadings, but for deer, stick with 150-grain bullets. Not much noise or recoil, and works well in short barrels.
