HTP: High Terminal Performance. This is the 40 S&W ammo you count on to save the day regardless of which handgun you own (provided it is chambered for 40 S&W, of course).Buy 155 Grain JHP
This cartridge is outfitted with the 40 S&W’s middleweight 155 grain bullet. Primed to a muzzle velocity of 1,205 fps out of a pistol barrel, it delivers good accuracy as it’s able to stay supersonic past 25 yards. At very close range the bullet transfers nearly 500 ft lbs of energy to its target – which is overwhelming – but even at 100 yards it exceeds the minimum energy threshold commonly advised for self-defense. The HTP JHP is designed to deliver up to double diameter expansion. In short, this is a round capable of punching a 4/5” wide hole into its target.
Remington loads their HTP rounds with first-quality brass cases to avert any feeding or extraction issues. Big Green also loads this ammo with their dependable and non-corrosive Kleanbore primers, as well as low-fouling powder to preserve accuracy and functionality of the handgun.Buy 155 Grain 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.
