History

Introduced jointly by Winchester and Browning Arms in 2021 specifically for the Browning X-Bolt and Winchester Model 70. The design goal was a short-action cartridge capable of launching the heaviest .277-caliber bullets — 162 to 170 grains — at velocities sufficient for long-range big game hunting. The 1:8 twist rate stabilizes bullets that traditional .270 Winchester and .270 WSM rifles can't handle. Hornady's 175-grain ELD-X factory load quickly became a benchmark for long-range hunting performance.
