Description
40 Smith & Wesson 150 grain FMJ– 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.
The Bullet
The jacketed hollow point (JHP) is designed to expand rapidly when hitting its target, which increases the effectiveness of the bullet and decreases the chances of over-penetration. Jacketed hollow points come in a massive variety, separated by shape, design or simply the company that manufactures them. JHP rounds will feed better than lead nosed hollow points in most weapons that use a magazine, whether it’s a pistol or rifle. The jacket has a much smoother surface, with less variation from bullet to bullet than traditional lead.
