In the 1970's the late Elgin Gates decided to designed a series of new Magnum cartridges. All the new cartridges were dubbed SuperMags 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 SuperMag revolvers in .357, .375, and
.445.
The second in the SuperMag series, the .375 SuperMag, like its smaller counterpart(the 357super magnum), is 1.610" in length and cartridges originally had to be made from .375 Winchester or .30-30 Winchester brass, cut to length and filed in a trim die. Now factory .375 SuperMag brass is available, but the .375 SuperMag has never been offered as a factory loaded ammunition. So it is a wildcat. |
