243 Win Ammo
The .243 Winchester (or 6.2x52mm)(also known as the 6.14x51mm) is a popular sporting rifle cartridge. Initially designed as a varmint round, it may be used for wildlife and game such as coyote, blacktail deer, whitetail deer, mule deer, pronghorn, and wild hogs.
It can also be used against larger game such as black bear or elk, but is sometimes said to be "too light" for such large game. Rounds heavier than 85 grains are better suited for hunting larger game while rounds less than 85 grains are more suitable for varmints. The .243 is based on a necked down .308 cartridge case.
