.500 S&W Magnum

.500 S&W Magnum (other times referred to as 12.7x41mmSR) is a .50 caliber semi-rimmed revolver cartridge that was developed by Car-Bon in joint with Smith & Wesson’s “X-Gun” engineering team. Smith & Wesson took on this project because they wanted to use the .500 S&W cartridge in their soon to be released Model 500 X-frame revolver at SHOT Show February 2003. When developing the .500 S&W Magnum there were two main purposes in mind. A hunting handgun cartridge capable of standing up to all North American game species, and to be the most powerful handgun cartridge to date. As a visual representation of the extreme levels of the power produced by .500 S&W Magnum, imagine a 16 pound bowling ball traveling at speeds of 70 miles per hour. That is roughly equivalent to the muzzle energy of a .500 S&W Magnum bullet fired from a typical commercial load! 

The .500 S&W Magnum has a maximum working pressure of 60,000 psi, although most factory ammunition is limited to 50,000 psi. This is done not only for safety reasons but it also plays a part in easier extraction of fired .500 S&W Magnum brass. SAAMI recommends a 6 groove barrel with each grove being 0.130 inches wide, a barrel with a bore diameter of 0.4983 inches, and a groove diameter of 0.4983 inches is also recommended for .500 S&W Magnum. The overall length of the .500 S&W Magnum cartridge is given as 2.300 inches by a variety of sources, some revolvers will not accept cartridges with bullets seated to this overall length. This happens because the cylinders of these particular revolvers are too short to accommodate the 2.300 inch overall length. Many of the firearms chambered in .500 S&W Magnum that had this issue have since been discontinued, one example is the Taurus Raging Bull 500. It experienced these issues because the cylinder was roughly 0.200 inches shorter than the S&W Model 500. 

Smith & Wesson accomplished their goal of developing the most powerful handgun cartridge with the .500 S&W Magnum, and is still considered to this day the most powerful by virtue of the muzzle energy it can generate. Bullet weights for the .500 S&W Magnum range anywhere from 265 grain up to 740 grain. The .500 S&W Magnum was always intended to just be a pistol caliber cartridge, Big Horn Armory changed this when they released the Model 89 lever action rifle. It’s been stated with great confidence that the .500 S&W Magnum (when used in the Model 89 platform) is capable of taking on any animal on earth. Even though the .500 S&W Magnum is not as common as some of the other pistol calibers, there is still a surprisingly amount of once fired brass available.
