40 S&W – 165 gr HST JHP – Federal Premium Law Enforcement – 50 Rounds
Federal’s Premium Law Enforcement HST line of JHP duty ammunition offers massive expansion! This duty load has a pre-skived bullet tip which causes the bullet to expand into large petals that cause a large permanent wound cavity. The unique design of this bullet actually forces the lead petals during expansion to protect the copper petals behind them. This results in increased weight retention allowing it to still achieve deep penetration through a variety of barriers prescribed by the FBI test protocols.165 gr HST JHP
During tests of the 9×19mm and .45 ACP ammunition, the FBI Firearms Training Unit’s special agent-in-charge, John Hall, decided to include tests of the 10mm Auto cartridge, supplying his own Colt Delta Elite 10mm semi-automatic, and personally handloaded ammunition. The FBI’s tests revealed that a 170–180 gr (11.0–11.7 g) JHP 10mm bullet, propelled between 900–1,000 ft/s (270–300 m/s), achieved desired terminal performance without the heavy recoil associated with conventional 10mm ammunition (1,300–1,400 ft/s (400–430 m/s)). The FBI contacted Smith & Wesson and requested it to design a handgun to FBI specifications, based on the existing large-frame Smith & Wesson Model 4506 .45 ACP handgun, that would reliably function with the FBI’s reduced-velocity 10 mm ammunition. During this collaboration with the FBI, S&W realized that downsizing the 10mm full power to meet the FBI’s medium velocity specification meant less powder and more airspace in the case. They found that by removing the airspace they could shorten the 10mm case enough to fit within their medium-frame 9mm handguns and load it with a 180 gr (11.7 g) JHP bullet to produce ballistic performance identical to the FBI’s reduced-velocity 10mm cartridge. S&W then teamed with Winchester to produce a new cartridge, the .40 S&W. It uses a small pistol primer whereas the 10mm cartridge uses a large pistol primer.165 gr HST JHP
