357 Herrett

New drawing Coming

The .357 Herrett is a wildcat cartridge designed by Steve Herrett and developed with the collaboration of Remington and wildcatter Ken Waters in the 1970s. The cartridge is based on a shortened and necked-up .30-30 Winchester case, tailored for use in the Thompson/Center Contender single-shot pistol.
The .357 Herrett was intended primarily for handgun hunters looking for improved performance over the .357 Magnum, offering higher velocity and energy for better effectiveness on medium-sized game such as deer. Typical bullet weights range from 110 to 200 grains, with the cartridge delivering impressive accuracy and stopping power at reasonable hunting distances.
The .357 Herrett is known for its versatility and the ability to use a wide range of bullet types and weights. However, being a wildcat cartridge, it requires handloading as factory ammunition is not commercially available. Handloaders can take advantage of its performance potential by tailoring loads to specific needs.
This cartridge has become somewhat of a niche option but remains popular among enthusiasts who own the Thompson/Center Contender and seek a powerful, accurate option for hunting or target shooting.
