The creation of the .357 magnum round in the 1930s has been attributed to three different men; Elmer Keith, Philip Sharpe, and D. B. Wesson. Created to be a revolver round, there was one driving force behind its creation; penetration. When the prohibition laws we put in place in the 1920s, bootleggers begin to find ways to out-smart law enforcement. It wasn’t long before they began using armor plating and vests in an effort to become bulletproof. Their thinking; if the round can’t get to them, they can’t be stopped.
After intense testing, it was discovered that a round travelling any slower than 1000 feet per second was useless against this armor. Thus, many rounds of the day were not effective. In fact, the only one before the .357 magnum that could penetrate the armor was the .38 Super Automatic by Colt. In fact, the .357 magnum was birthed by experimenting with different load sizes inside of a .38 super casing.
Through-out the early 1930s, Keith, Sharpe, and Wesson experimented with several load sizes and projectiles. It was soon discovered that, though you could chamber a .357 magnum in a gun designed for a .38 super round, it was not safe considering the drastic rise in power. Hence why the .357 magnum casing is only 1/8 an inch longer. Nowadays, the .357 magnum is popular as a back-up weapon for many hunters and outdoorsman due to its ability to bring down big game.
