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 shot this brand of ammo before, it has always performed well in my semi-auto without jaming, and is very accurate in my particular weapon.

Not at the Federal level. God knows what kind of restrictions exist in some of the more helsilh SSR's, but here in Tennessee, your ammo purchases are restricted only by your bank acount and the Gross Vehicle Weight Rating of your ride.

Top of the line on all categories !!!

Charles said:
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.

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

Ran a box of this ammo through a Springfield XDM .40 at the range today with no problems. Nice price for when you want to send something down range other than a .22LR. I'll be buying more. Thanks Ammo.com!!

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.
