History of 327 Federal Magnum Ammo

In 2008, Federal Premium Ammunition and Sturm, Ruger & Company developed the .327 Federal Magnum to improve on the .32 H&R Magnum. This cartridge features a .312-inch diameter lead bullet in a 1.20-inch straight-walled, rimmed casing, resulting in a total length of 1.47 inches.

The .327 Federal Magnum achieves muzzle velocities up to 1,500 fps and energies up to 500 ft·lb, surpassing .38 Special and most 9mm rounds, and even matching many .357 Magnum loads. With a SAAMI pressure rating of 45,000 psi, it outperforms the .357 Magnum (35,000 psi) and .44 Magnum (36,000 psi), making it a powerful and efficient self-defense round.
