40 Smith & Wesson 155 Grain Hornady XTP– The .40 S&W is a rimless pistol cartridge developed jointly by major American firearms manufacturers Smith & Wesson and Winchester. The .40 S&W was developed from the ground up as a law enforcement cartridge designed to duplicate performance of the Federal Bureau of Investigation‘s (FBI) reduced-velocity 10mm Auto cartridge which could be retrofitted into medium-frame (9mm size) semi-automatic handguns. It uses 0.40-inch (10 mm) diameter bullets ranging in weight from 105 to 200 grains.
The popularity of the .40 S&W accelerated with the passage of the now-expired Federal Assault Weapons Ban of 1994 which prohibited sales of pistol or rifle magazines that could hold more than ten rounds (cartridges), regardless of caliber. Several U.S. states, and a number of local governments, also banned or regulated so-called “high capacity” magazines. As a result, many new firearm buyers limited to purchasing pistols with a maximum magazine capacity of 10 rounds chose pistols in the .40 S&W chambering instead of smaller-diameter cartridges such as the 9x19mm (9mm Luger or 9mm Parabellum).
The .40 S&W case length and overall cartridge length are shortened, but other dimensions except case web and wall thickness remain identical to the 10mm Auto. Both cartridges headspace on the mouth of the case. Thus in a semi-auto they are not interchangeable. 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 and 500 foot-pounds of energy, depending on bullet weight. Both the .40 S&W and the 9mm Parabellum operate at a 35,000 pounds per square inch SAAMI maximum, compared to a 21,000 pounds per square inch maximum for .45 ACP.
eXtreme Terminal Performance
Designed for hunting, self-defense and law enforcement applications, the XTP bullet demonstrates the kind of accuracy that led many competitive shooters to adopt it. Reliable performance makes the XTP the most popular handgun bullet for both target shooters and hunters. But it’s the stopping power of the XTP bullet that has truly built its world-class reputation. From the onset, XTP bullets were specifically designed to expand reliably at a wide range of handgun velocities to deliver deep penetration with every shot.
Our 40 S&W 155 grain XTP ammunition is second to none. With the tightest loading tolerances in the industry through our proprietary formulas and 100% hand-loading techniques- this round of ammunition is designed for superior accuracy, reliability and consistency when you shoot them over other factory produced rounds on the market.
