The 264 Winchester Magnum was introduced by Winchester around 1958 for use in the Model 70 Winchester
bolt-action rifle.
The cartridge was created be necking down the .458" or 458 Winchester to accept 6.5 mm or .264" or 264
caliber projectiles, making this cartridge the first 6.5mm American cartridge since the .256 Newton in 1913.
With velocities to over 3,800 feet per second and energy over 3,000 foot pound per square inch, this was a
great long range mountain or plains, big game caliber, if not a bit hard on barrels
