The .243 Winchester (6.2×52mm) is a popular sporting rifle cartridge. Developed as a versatile short action cartridge to hunt both medium game and small game alike, it “took whitetail hunting by storm”2 when introduced in 1955, and remains one of the most popular whitetail deer cartridges.
It is also commonly used for harvesting blacktail deer, pronghorns and mule deer with heavier rounds, and is equally suited to varmint hunting with lighter rounds. The .243 is based on a necked down .308 Winchester, introduced only three years earlier. Expanding monolithic copper bullets of approximately 803 to 8545 grains or traditional lead rounds of 90 to 105 grains with controlled expansion designs are best suited for hunting medium game, while lighter rounds are intended for varmints.67
In at least ten U.S. states8 and the United Kingdom,9 the .243 or similar cartridges are the smallest bore cartridges that are legal for hunting deer; this has been revised in the UK to allow Muntjac and Chinese Water Deer to be taken with .22 (5.56mm) chambered weapons.10
The cartridge can be extremely accurate to 300 yards (270 m) and beyond, but may not retain enough terminal energy to reliably drop medium game at that distance.41112 Highly experienced hunters use the .243 Winchester to routinely drop bucks up to 250 pounds (110 kg),2 while less experienced hunters can be just as capable with the .243 because of its very low recoil yet high velocity.71113 hunting applications, the cartridge is popular with target and metallic silhouette shooters for those same recoil and velocity properties, with superb accuracy.12
The .243 Winchester has regularly made the top five of rankings for “Best Whitetail Deer Hunting Cartridges” from sources such as Field and Stream14 and Outdoor Life,215 and its widespread popularity (called the “whitetail hunter’s favorite” by the Browning Arms Company16 and “American favorite” by American Rifleman7) assures chamberings in newly manufactured offerings of not only bolt-action rifles, but also semiautomatic rifles (e.g., Browning BAR), lever action rifles (e.g., Henry Long Ranger), and pump action rifles (e.g., Remington 7600).2
Gun Digest estimates that (as of the end of 2018) the .243 Winchester is the second-most popular of all hunting rifle chamberings (after the long action .30-06).17 Commentators such as popular ammunition author Chuck Hawks have opined that the .243 Winchester (as a “6mm NATO” round) should replace the 5.56×45mm NATO (.223 Remington) for most United States Armed Forces use cases but the .243 has, as of 2021, never been used as a military cartridge.18
With very little recoil, even less25 than that of the .30-30 Winchester cartridge introduced sixty years earlier, the .243 brings higher chamber pressures, larger powder volumes, and sharply tipped bullets, which combine to lend the .243 more muzzle energy and far greater downrange energy than the .30-30 is able to achieve.2 The .243 Winchester has also been found to shoot flatter and more accurately than the 7mm-08 Remington out to 500 yards, with less recoil yet also less terminal energy.11.243 has the lowest recoil factor among small bore deer hunting cartridges.26
