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 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.

  • JoelDug said:

    What is there to say... Sellier and Bellot is great ammo. What is not to like? This ammo alway fires well.

    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.
