History 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.

    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.

    Have run over 14,000 rounds(yes...that's fourteen-thousand- plus) through my Sig P229 and I believe maybe two or three were misfires. I am very satisfied with the product.

  • Tom said:

    I am a returning customer the ammo is always great and priced below others out there shipment couldn't be easier . This is a great company to do business with

  • Joe said:

    What a mess, jams, powder build up.... this ammo did everything it could to foul my weapon. I blew threw cheaper Russian AMMO in my Ruger SR40C no issues, cleaning was average. As I closed in on 80 rounds of this Remington ammo you could tell it was going to be a long afternoon, powder all over the muzzle, then the jams started and cleaning took forever! Would not recommend.
