The .300 Winchester Magnum
Nation Year Max. press.
U.S.A. 1963 64000psi
This is a very high powered long range cartridge which is also accurate enough to be developing quite a reputation as a long range sniping cartridge. With the exception of the .300 Weatherby, this is the most powerful .30 cal cartridge in the world, and even the famed Weatherby gets a run for it's money. This round is accurate out to 1000 yards (that's ten football fields), and at that range has more energy than the .44 Magnum has at the muzzle, with better ballistics. There are some loads using lighter bullets (as low as 110 grains), but where this round really shines is in it's ability to launch heavy bullets long distances.
