The .357-44 Bain & Davis is a wildcat cartridge, developed in the 1960s by Keith Davis and named after the Bain & Davis Gun Shop in California. It is essentially a .44 Magnum case that has been necked down to accept a .357-inch bullet. This combination aims to provide higher velocity and flatter trajectory compared to the standard .357 Magnum cartridge, thereby improving performance for handgun hunting and long-range shooting.
Typical use cases for the .357-44 Bain & Davis include hunting medium-sized game and target shooting, where its higher velocity can offer advantages in terms of energy transfer and accuracy. Reloading is necessary for this cartridge since it is not commercially manufactured, and it requires both .44 Magnum brass and .357-caliber bullets. Firearm modifications, such as rechambering a revolver or custom barrel work, are often necessary as well.
