History of 327 Federal Magnum Ammo
In 2008, Federal Premium Ammunition collaborated with Sturm, Ruger & Company to develop the .327 Federal Magnum, making it a relative newcomer to the firearms world. The companies’ joint goal was to improve on the .32 H&R Magnum, which was never loaded in a factory round to its full capacity.
The .327 cartridge features a .312-inch diameter lead bullet that sits in a straight-walled, rimmed casing that measures 1.20 inch – one-eighth inch longer than the .32 H&R Magnum case (the parent casing on which it is based). Together the cartridge measures 1.47 inches in total length.
Muzzle velocities for the 85 or 100 grain (gr) bullets, which are most commonly loaded in this cartridge, can reach a velocity of up to 1,500 feet per second (fps). Muzzle energies, as a result, can be as much as 500 foot pounds (ft·lb). The energy levels of the .327 Federal Magnum exceed any commercially available .38 Special and most 9mm ammo. The .327 Federal Magnum can even meet the same energy levels as many .357 Magnum loads.
When it comes to pressure, according to the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) standard, the .327 Fed Mag has the highest pressure of any other commercial self-defense round at 45,000 pounds per square inch (psi). Compare this to other Magnum cartridges like the .357 Magnum, which has a max pressure of 35,000 psi, and the .44 Magnum with a max pressure of 36,000 psi, and it’s easy to see the difference in pressure.
These features led to an ammunition that accomplished exactly what its designers set out to do, create a round that far exceeds its parent in both power and performance.
