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.

    Works good. No jams or misfires

  • Paperbanger said:

    Looking for some .40 cal you can feed your pistol with total confidence? Fill your magazines with the HST JHP from Federal! My Sig and I spent an afternoon punching holes with these, along with three other brands. We know there are some brands okay for range practice, because a misfeed or misfire doesn't matter much. But it was clear from the outset that if you carry, these are the guys you want to take with you. Never a misfeed or misfire, and accurate to a gnat's eyelash. I figure if it's my life and perhaps the lives of my loved ones on the line, I'll have enough to worry about without fighting the bad guys and my ammo problems at the same time.
