Buy Winchester .40 S&W 165 Grain FMJ
The Winchester 40 s&w 165grain has set the world standard in superior handgun ammunition performance and innovation for more than a century. And to millions of hunters and shooters worldwide, the name “Winchester” means quality and performance – and the most complete, versatile and high-performance line of handgun ammunition in the world.
The .40 S&W cartridge has been popular with law enforcement agencies in the United States, Canada, Australia, and Brazil. While possessing nearly identical accuracy, drift and drop as the 9mm Parabellum, it also has an energy advantage over the 9mm Parabellum and .45 ACP, and with a more manageable recoil than the 10mm Auto cartridge. Marshall & Sanow (and other hydrostatic shock proponents) contend that with good jacketed hollow point bullets, the more energetic loads for the .40 S&W can also create hydrostatic shock in human-sized living targets.
Based on ideal terminal ballistic performance in ordnance gelatin during lab testing in the late 1980s and early 1990s, the .40 S&W earned status as “the ideal cartridge for personal defense and law enforcement”. Ballistically the .40 S&W is almost identical to the .38-40 Winchester introduced in 1874, as they share the same bullet diameter and bullet weight, and have similar muzzle velocities. The energy of the .40 S&W exceeds standard-pressure .45 ACP loadings, generating between 350 foot-pounds (470 J) and 500 foot-pounds (680 J) of energy, depending on bullet weight. Both the .40 S&W and the 9mm Parabellum operate at a 35,000 pounds per square inch (240 MPa) SAAMI maximum, compared to a 21,000 pounds per square inch (140 MPa) maximum for .45 ACP.
.40 S&W pistols with standard (not extended) double-stack magazines can hold as many as 16 cartridges. While not displacing the 9mm Parabellum, the .40 S&W is commonly used in law enforcement applications in keeping with its origin with the FBI. Select U.S. special operations units have available the .40 S&W and .45 ACP for their pistols. The United States Coast Guard, having dual duties as maritime law enforcement and military deployments, has adopted the SIG Sauer P229R DAK in .40 S&W as their standard sidearm.
The .40 S&W was originally loaded at subsonic velocity (984.25 ft/s (300.00 m/s)) with a 180 grains (11.7 g) bullet. Since its introduction, various loads have been created, with the majority being either 155, 165 or 180 gr (10.0, 10.7 or 11.7 g). However, there are some bullets with weights as light as 135 gr (8.7 g) and as heavy as 200 gr (13.0 g). Cor-Bon and Winchester both offer a 135 gr (8.7 g) JHP and Cor-Bon also offers a 140 gr (9.1 g) Barnes XPB hollow-point. Double Tap Ammo, based in Cedar City, Utah, loads a 135 gr (8.7 g) Nosler JHP, a 155 gr (10.0 g), 165 gr (10.7 g) and 180 gr (11.7 g) Speer Gold Dot hollow-point (marketed as “Bonded Defense”), a 180 gr (11.7 g) Hornady XTP JHP, and three different 200 gr (13.0 g) loads included a 200 gr (13 g) Full Metal Jacket (FMJ), a 200 gr (13 g) Hornady XTP JHP and Double Tap’s own 200 gr (13 g) WFNGC (Wide Flat Nose Gas Check) hard cast lead bullet; the latter specifically designed for hunting and woods carry applications.
