- The .270 Winchester is a rifle cartridge that has been helping hunters bring down game since 1925. It was developed by Winchester Repeating Arms Company and is known for its flat shooting, moderately powerful capabilities. The .270 Win. moves a little faster due to its lighter projectiles and larger case capacity, which is basically just a necked-down .30-06.When brought to market in 1925, the .270 Win. was the best long-range big game round in existence. It shot flatter than anything else approaching it and had less recoil than other cartridges of the time. Today, it remains one of the most popular hunting rounds with versatile applications for both small and large game animals.
