Overview of 40 Cal (S&W) Ammo
The .40 S&W cartridge was developed to provide more stopping power than the 9mm Parabellum and better handling than the .45 ACP. A team from Smith & Wesson and Winchester achieved these goals, creating a rimless, 10x22mm round with a .40-inch (10mm) bullet weighing between 105 and 200 grains (gr). This cartridge offers enough stopping power for home defense and concealed carry while being manageable for shooters of various sizes.

This is my first purchanse from Ammo.com, but it won't be my last. I've ordered ammo from several web sites, all promising the lowest price for the same ammo. In a direct comparison, this is the lowest price for exactly the same ammo. The ammo came well packaged in 50-round sets and fired flawlessly. Hard to complain about that.

Not at the Federal level. God knows what kind of restrictions exist in some of the more helsilh SSR's, but here in Tennessee, your ammo purchases are restricted only by your bank acount and the Gross Vehicle Weight Rating of your ride.
