ANSI technical cartridge drawing
The legendary Elmer Keith is given credit for the 44 Rem Mag - his research throughout the 1940s, and avocacy in the 1950s, arguing a need and place for a handgun and cartridge capable of dropping most if not all North American game.
Although Keith did his research with hugely overpressure 44 Special rounds in comparably very short life expectancy 44 Special wheelguns, in order to guarantee the new 44 Mag rounds couldn't be chambered in a 44 Special (15000 CUP rated) firearm, (besides garnering an additional 4.2 grs of capacity), the 44 Special case was lengthened by .125". The 44 Mag is pressure rated at 40000 CUP (36000 psi).
In addition to its established reputation as significant deer and black bear hundgun hunting round, the 44 Mag can also be loaded (back) down to 44 Special velocities and used as a target round.
