Jamison Brass and Ammunition currently has a full quality control and quality assurance laboratory in house. Our lab consists of all the gauges and tests needed to meet all caliber tolerances. We follow all specifications according to SAAMI and CIP standards. The tests and measurements we perform on our products assure that we produce the highest quality possible. Testing and analysis of our products begin from the moment we receive our raw materials all the way to the finished product as it is being packaged for sale.
Ammunition is constructed in close conjunction with American powder companies to ensure safe operating pressures and performance. Ammo assembly is handled with the same care as loading at home. Using tight tolerances on charge variation, seating, and crimping. Loaders check often to safe guard quality and consistency
The information below comes from our Gun Caliber Dictionary and is for
general reference only. It does not describe the specifications of this
particular item.
Designed by Winchester and introduced by Winchester and Smith & Wesson in 1990, the 40 S&W was designed as a "compromise" semiautomatic pistol cartridge that would offer more performance than the 9mm Luger (9x19)…but would produce less recoil and allow higher magazine capacity than the 45 ACP. Few compromises in the firearms world have ever worked as well. From a manufacturing standpoint many pistols designed for the 9mm could be re-engineered to handle the larger cartridge; in a short time it has become a standard issue in the law enforcement community. Using a .400-inch bullet of from 135 to 180 grains from a .850-inch cae, the .40 S&W produces up to 1205 fps, and although recoil is greater than the 9mm, it is easier to shoot than the 45 ACP, and its greater velocity and smaller bullet diameter aid penetration.
