The fate of cartridges with metric names changed dramatically in 1962 when Remington introduced the 7mm Remington Magnum in the then-new Remington Model 700. The spiffy new rifle and the cartridge’s terrific performance on big game, great accuracy, flat trajectory, and modest recoil won over American shooters who recognized a good thing when they saw it. While Winchester had launched the .264 Winchester Magnum in 1959, its acceptance was minimal and was buried by the 7mm Rem. Mag.
