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.

Dave said:
Have used 200 of the 250 rounds purchased with NO problems at all in a Taurus or in my Hi-Point. I will be back for more as it is a great practice round!

Shot ammo in a Glock 27 Gen 4 with very little problem. Ammo jammed a couple of times, but I don't think the ammo was the problem. I will buy more Prvi Partizan ( PPU) ammo when possible in .40 cal, 9mm, and 357 sig. Great stuff. Shoots cleaner than most other I have found.

DANIEL said:
These are great for my line of work.

Richard said:
Shot well,no feed problems Shot with wooden back stop The bullet did not expand as what I expected... Definitely good penetration

Joel said:
Ammo would look better if the aluminum casing was replaced with brass.

This is my first purchanse from Ammo.com, but it won't be my last. I've ordered ammo from several web sites, all promising the lowest price for the same ammo. In a direct comparison, this is the lowest price for exactly the same ammo. The ammo came well packaged in 50-round sets and fired flawlessly. Hard to complain about that.

Fine performance

MICHAEL said:
Very good round for the money my gun loves a hotter round I shoot a hi point 40 s/w it just runs better with a hot load other than that its a sweet round for any 40 out there I'll buy more but a hotter load.

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.

James said:
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.

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.

Works good. No jams or misfires

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.

Investigator Man said:
I’ve used this Ammo as my duty Ammo as well as my full time carry Ammo for all occasions. It’s stopping power is second to none.. highly reliable and this Ammo will deliver, I have this Ammo in 9mm .40 as well as in .38 / .357. I motto is : Don’t ever buy cheap Ammo when your life depends on it!!
