Overview of 243 Ammo

In 1955, Winchester introduced the .243 for two rifles: the bolt-action Model 70 and the lever-action Model 88. Known for its efficiency, the .243 cartridge enjoys a positive reputation today, with all major American ammo manufacturers selling it in an extensive array of bullet weights and types.

Most major firearms manufacturers have at least one weapon chambered for the .243 Winchester. It’s the only 6mm cartridge that ever effectively captured the imagination of the American ammunition market.
