The .243 Winchester (6×52mm) is a popular sporting rifle cartridge. Initially designed as a target/varmint round, it may be used for animals such as coyote, blacktail deer, whitetail deer, mule deer, pronghorn, and wild hogs. It can also be used against larger animals such as black bear or elk but is sometimes said to be “too light” for such large animals. Rounds of at least 90 grains are better suited for hunting larger animals while rounds less than 90 grains are more suitable for varmints. The .243 is based on a necked down .308 cartridge case. It is very popular with target shooters, Metallic Silhouette, and long range shooters, because of its accuracy and low recoil.
