The .401 Herter Powermag was introduced in 1961 by the Herter's Inc.
Company of Waseca, Minnesota for use in
the Herter's Powermag single-action revolver.
No other company chambers this caliber, making it a now "Obsolete,
Proprietary Cartridge".
The 41 Herter Powermag is very similar in power to the 41 Remington
Magnum, however they are not interchangeable.
