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.

Capt. Miller said:
We use these to qualify our department so we go through hundreds of rounds. This stuff barely dirty's the gun and has not misfired or jammed yet.
-
Gene said:
When you pull the trigger the ammo goes "bang!" What more can you ask? It burns clear, leaving gun fairly free of residues and carbon.

It was easy to order and had no problems comparing products. The package was heavy but taped and secured well. It arrived in the normal amount of time and performed well at the range. Good value.

Charles said:
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.

Paul said:

Steiny said:
I had been hoping for prices to drop before I ran out of my existing supply but that wasn't happening. Then I ran across ammo.com and found these. I'd never had any of this brand before but I'm quite satisfied with the product and ammo.com. All my future purchases will be through ammo.com.
