About 243 Ammo
243 Winchester is known as one of the best small to medium-game hunting cartridges in America.
Introduced in 1955 and became popular in the industry as one of the best whitetail deer cartridges.
The .243 is based on a necked down .308 Winchester, introduced only three years earlier.
The cartridge can be extremely accurate to 300 yards (270 m) and beyond but may not retain enough terminal energy to drop a medium game at that distance reliably.
Performance-wise, the .243 Winchester closely matches the 6mm Creedmoor, but the .243 Win has more bullet and casing options.
Its accuracy, mild recoil, and wide ammo selection make it a great choice for hunting deer, coyotes, and feral hogs.
