Based on the .308 Winchester, the .358 Winchester was introduced by Winchester in 1955 for use in lever and bolt-action rifles. While it had not seen the widespread popularity as the other .308 -based cartridges, its brush busting capability still makes it an excellent choice for hunting. With the recent rise in popularity of AR-10 style rifles, the .358 Winchester is starting to be chambered in it because the .358 gives the AR-10 just a little more thump than the .308 Winchester
