It is intended to provide the power of a .357 Magnum in six-shot, compact revolvers, whose cylinders would otherwise only hold five rounds. The .327 has also been used in full-sized revolvers with a capacity of seven rounds or more. The .327 Federal Mag is an example of a "super magnum", because it is a magnum of a magnum, the .32 H&R Magnum.https://gunnewsdaily.com/327-federal-magnum/ 327 Federal Magnum: A Good .357 Magnum Alternative? 31 December 2022 Development Introduced by the Federal Cartridge company, now known as Federal Premium Ammunition, the .327 Federal Magnum was an attempt to improve on the .32 H&R Magnum introduced in 1984. Like the .32 H&R, the .327 Federal is a lengthened version of the original .32 S&W cartridge, which dates back to 1878. In 1896, the .32 S&W Long was introduced, which generated slightly higher velocities. The introduction of the .32 H&R increased pressures from 15,000 psi MPa on to 21,000 CUP, giving velocities of approximately 1200 ft/s on.Mann Richard A. Is The .327 Federal Magnum The Best All-Purpose Magnum? https://gundigest.com/gear-ammo/ammunition/is-the-327-federal-magnum-the-best-all-purpose-magnum 20 February 2019 Gun Digest 17 December 2018 Based on the .32 H&R Magnum, with a .125 in on longer case, a strengthened web at the base of the case, thicker case walls, and different heat-treatment and metallurgy, the .327 Federal can be loaded to much higher pressure levels (45000 psi MPa on) than its predecessor (21,000 CUP).Pearce, Lane, "Reloading the .327 Federal Magnum", Shooting Times Magazine, 4 January 2011 The .327's actual bullet diameter is .312 in mm 2 on, and it achieves muzzle velocities up to 1400 ft/s m/s on with 100 gr g+oz on bullets, and up to 1300 ft/s m/s on with 115 gr g+oz on bullets, when fired from the 3.0625 in on (78 mm)-barreled Ruger SP101 revolver.Ballistics By The Inch .327magnum results. While perceived recoil exceeds that of the .32 H&R, revolvers in .327 Federal are much easier to control than equivalent models chambered in .357 Magnum. Comparing the two calibers, Chuck Hawks says, "There is no doubt that, for most shooters, the .357 Magnum produces uncomfortable recoil and muzzle blast."http://www.chuckhawks.com/327_federal.htm First Look: .327 Federal Magnum Revolver Cartridge Chuck Hawkshttp://www.handloads.com/misc/saami.htm SAAMI Pressure Specs dead https://web.archive.org/web/20070928121135/http://www.handloads.com/misc/saami.htm 28 September 2007 The .327's recoil energy is 3.08 ft·lbf J on for an 85 gr g+oz on jacketed hollowpoint (JHP) load, 5.62 ft·lbf J on for the 115 gr g+oz on JHP, and 5.58 ft·lbf J on for the 100 gr g+oz on softpoint (SP). For comparison, the figures are 1.46 ft·lbf J on for an 85 gr g+oz on .32 H&R Magnum load and 7.22 ft·lbf J on for a 125 gr g+oz on .357 Magnum load.
