40 Cal Ammo

.40 Smith & Wesson ammo is a widely used cartridge for concealed carry and law enforcement. Although it has a reputation for severe recoil, the .40 S&W offers excellent ballistic potential in trained hands. It is based on a 10mm Auto casing shortened to fit into handguns originally designed for the 9mm Luger.

Most 40 cal loads fire a 165 or 180 grain bullet at 950-1100 feet per second; for those who want more reliable expansion or are concerned with overpenetration, lighter bullets in the 135-155 grain range (with corresponding increases in velocity) are also available.

Many manufacturers offer handguns in this caliber, in part due to its intentional compatibility with existing 9mm designs. Notable .40 S&W pistols include Smith & Wesson's own M&P40, Ruger's SR40C, the Beretta Px4 Storm, the Springfield XD, and even some variants of the Browning Hi-Power.

You'll find in-stock 40 cal ammo for sale here at Widener's from great brands like Federal, Winchester, PMC, Magtech and more so you can focus on your next range trip and not worry about the reliability of your rounds.

    Winchester's Winclean brand is made to give safe and effective rounds for indoor shooting. Most jacketed bullets have exposed lead at the back of the projectile, but these rounds are Brass Enclosed Base, or BEB. BEB does not give off lead residue, which means no toxic lead chemicals. This makes BEB more reliable for indoor shooting where lead particles can accumulate.

    These bullets are excellent for indoor target practice. They have a muzzle velocity of 990 feet per second and a muzzle energy of 392 foot-pounds. They can even be used for distance practice, as they maintain a speed of 943 feet per second after 50 feet.

    Winchester is one of the most iconic brands in the American firearms industry, but they are also a modern innovator in shooting technology. As the Winclean brand demonstrates, this company builds high-quality ammunition products that are designed with the precision and specifications that modern shooters demand.
