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.

    No jams, zero feed issues. Shoots clean . 4 star for performance was only due to it being 40 target ammo and the grouping wandered about 1/2 inch up or down. Over all was still in the mass zone at 21 and at 30 feet .

    This round almost has to much powder. Looking at a spent cartridge the primer firing pin mark is almost pushed back out.

    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.
