The .500 Smith & Wesson Magnum cartridge is nothing to mess around with. This is why Hornady created a very impressive load for this cartridge. The bullet is tipped with a 300-grain Flex Tip expanding projectile. This load is rated for 2050 feet per second, which equates to a whopping 2868 foot-pounds of energy at the muzzle. This is a figure normally reserved for rifle caliber cartridges, but this .500 S&W load delivers the goods.
Designed to cause maximum soft tissue damage, the Flex Tip Expanding projectile used in this load is the next evolution of the hollow point. As some may have experienced, the hollow point bullets of years past may have had some issued with achieve proper expansion on a consistent basis. This lack of consistency was, in part, due to the hollow point cavity becoming clogged. The Flex Tip technology has found a solution to this issue. A soft polymer tip is placed in the cavity of the hollow point to prevent clogging and thereby reducing the rate of failed expansion. This results in consistently large wound cavities that have the effect that you are looking for.
