Do you like training indoors, at ranges with rocky backdrops, or with steel targets? Then you ought to keep your lungs lead-free and your face safe from shrapnel courtesy of Speer’s Lawman 40 S&W ammo. 125 Grain RHT Frangible
This round sports a 125 grain RHT projectile. It’s a frangible bullet, made of compressed metal powder instead of the traditional FMJ’s solid copper and lead. When a frangible bullet connects with a steel target or other hard surface it instantly crumbles to bits rather than threaten people nearby with splash-back or a ricochet..
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.125 Grain RHT Frangible
This round’s a natural choice for training indoors where you’re surrounded by concrete walls. Even better still, its lead-free Clean Fire primer and RHT bullet won’t cloud up a room with lead vapor – you can breathe easy when you fire Lawman ammo!
This round’s 125 grain bullet lets Speer load it to a blistering fast 1,300 fps muzzle velocity. And although its bullet and primer may be unconventional, its new production brass case is still perfect for handloading once it’s emptied out.
