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.

I'm happy with the prices and delivery times; My only complaint is i would rather the products come in unmarked boxes, since I am in the process of stockpiling ammo against the future laws of our state., I would rather no one knows what I'm purchasing, and having delivered.

Prompt service on my order and the ammo performed as expected. Great savings buy from ammo.com as opposed to retail.

Good performance and good value. I've gone through 200 rounds so far and only found one round that was damaged. I'm not sure what happened but I couldn't use it.
