History of the 375 Super Mag cartridge:
This cartridge stared out as a wildcat cartridge in the 1970’s designed by the late Elgin Gates, who decided to designed a series of new Magnum cartridges.
All the new cartridges were dubbed Super Mags by Gates and were 1.610″ in length, or about three-tenths of an inch longer than standard Magnum Cartridges.
Mr. Gates made up cartridges in .357, .375, .44, .45, .50, and .60 caliber.
In the 1980s with the help of Eligan Gates, Dan Wesson Arms produced Super Mag revolvers in .357, .375, and .445.
The second in the SuperMag series, the .375 Super Mag., like it’s smaller counterpart the 357 Super Mag. is 1.610″ in length and cartridges originally had to be made from .375 Winchester Magnum or .30-30 Winchester brass, cut to length and filed in a trim die.
This is factory made .375 Super Mag. brass but the .375 Super Mag has never been offered as a factory loaded ammunition.
