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 have only shot about 150 rnds through the gun, and the only hiccup was a few jammings that I believe were caused by an off brand 25 rnd. capacity clip.

I have never had any type of problem with Sellier & Bellot ammunition. It has always functioned exactly as it should.
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.
Bene said:
Bought 4 boxes. cycled flawlessly thru my Glock. Excellent value.

Greta product! A little expensive per shell, but when shells can't be purchased locally, I suppose the additional is expected. Still can't find all caliber ammo, even at ammo.com.

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

Perfect!!
Plinker Hit it Again said:
Every chambered round work as it should of, Down range and hit the target (could have been the gun; you be the judge). 500 rounds not a single miss fire, blasted the entire center out of the target at 15 yards, 2 1/4" group at 50 yards, 30 rounds 30 hits on the 100 yard target (4 in the center orange) and I am not a good shot. Brand new 40 S&W Hi Point Carbine only had it 3 weeks 4 X 12 X 44 Vortex Scope (Quite a Plinking machine; and so much fun) Great Ammo

Bullet Points: 40 Cal Ammo

A leading cartridge among the FBI and law enforcement agencies in the United States, the .40 Smith & Wesson gives police the capacity of the 9mm and the power of the .45 – also making it popular among civilians for self-defense and sport shooting.
.40 S&W ammo has also been adopted by the U.S. Coast Guard as its primary issue sidearm, due to its balance of muzzle energies and magazine capacity.
Civilians have adopted .40 S&W ammunition for many of the same reasons law enforcement has. Its mix of magazine capacity, muzzle energy and limited recoil make it ideal for home defense and concealed carry. Find .40 S&W ammo for sale in a variety of quantities and bullet types.
