The .375 Supermag, also known as .375 Super Magnum, is a high-velocity, high-power revolver cartridge. It was developed for use in large-frame revolver designs, like those made by Dan Wesson Firearms. The .375 Supermag is essentially an elongated version of the .357 Magnum, providing greater case capacity which allows for more powder and subsequently higher velocity and energy.
Primarily used for hunting medium to large game, it offers deep penetration and powerful impact. Due to its high recoil and large size, it is typically favored by experienced shooters and hunters who require a heavy-duty round for revolver hunting scenarios. The cartridge is less common than mainstream calibers and generally requires specialty firearms designed to handle its high-pressure load.
For handloaders, the .375 Supermag offers flexibility in terms of bullet weight and powder types, allowing customization for specific applications, from target shooting to big game hunting.
