The .243 Winchester cartridge, based on the necked-down .308 Winchester case, is a popular choice among varmint and deer hunters. Its relatively light recoil and flat trajectory make it suitable for long-range shooting. Common bullet weights range from 55 to 105 grains, offering versatility for various game and target sizes.
This cartridge’s effectiveness stems from its balance of manageable recoil and effective terminal ballistics. Introduced in 1955, it quickly gained popularity due to its inherent accuracy and suitability for both small and medium-sized game. This enduring popularity has led to widespread ammunition availability and a wide selection of rifles chambered for it. The inherent accuracy and moderate recoil also make it a viable option for competitive target shooting disciplines.
