The .243 Winchester cartridge has been on the market for 70 years now. I first used it as a young hunter in the mid to late 70’s. Developed by Winchester as a versatile short action cartridge for hunting medium big game it was immediately put to use by deer hunters when introduced in 1955. It also quickly became popular as a varmint hunting cartridge.
Today, it stands out as one of the most favored cartridges for whitetail, mule deer, pronghorn, and a wide variety of small to medium sized African plains game.
Specs: .243 Winchester

The cartridge is based on a necked down .308 Winchester, which came on the market only three years earlier in 1952. Today with the advent of expanding monolithic copper bullets in 80 to 85 weight grain class or the continued availability of jacketed rounds of 90 to 105 grains there are ample choices for any medium big game hunting need.
I relied on 243 Win with 100 grain bullets for most of my big game hunting back in the 1970’s and 80’s. One of my favorites was the old standby, Remington 100 grain Core-Lokt. But today, as mentioned, there are a wide range of .243 ammo choices for every need.
Ballistic Capabilities of .243 Win
As to performance and comparisons, the .243 Winchester is in the same category as the newer 6mm Creedmoor (developed in 2007) however, the .243 Win has more bullet and casing options. It also delivers more factory ammo offerings.
With very minimal recoil, even less than that of the 30-30 Winchester cartridge, the .243 gives higher chamber pressures and larger powder volumes. The .243 muzzle velocity comes in anywhere from about 2800 feet/second up to 3900 feet/second from factory-loaded expanding ammunition depending on bullet weight and barrel length.

.243 Is Great For Young Hunters

We consider .243 Winchester an ideal first rifle for young hunters in part due to the varied action choices and milder recoil. Bolt actions lead the offerings, however selections in semi auto, lever, and single shot break open models give the young hunter a broad spectrum to choose from. Henry Repeating Arms offers excellent rifles chambered in .243 of both the lever and break open actions.
Aside from Henry, a wide selection of .243 Winchester caliber rifles is available today from companies such as Savage, Winchester, Browning, Ruger, Mossberg, Remington, and Christensen Arms to mention but a few.
Final Thoughts
The .243 has been around for 70 years now and I have no doubt it will be around for decades to come. It is a pleasure to shoot and provides excellent accuracy when you find the right ammo for your particular rifle. I still enjoy shooting this caliber today and if you have never owned a rifle in .243 Winchester you owe it to yourself, kids, and grandkids to give it a try!
