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.

Good Ammo
Rick M said:
Performed flawlessly on my Kahr CM40, Glock 23, and Berreta Cx4. The Kahr is finicky but no problems, plus it burns as clean as the higher end name brand ammo. This is my range ammo from now on. I'm not that accurate myself, so I couldn't tell you about the accuracy.
Steve said:
Went to the range and shot over 250 rounds from my Walther PPQ40. Not a single jam or misfire. Will definitely buy more!

See above.
knox86 said:
I got 500 rounds about 6 months ago and so far haven't had a single jam or malfunction at the range out of my XDm. could be a little cleaner but i've worse out of new non reman ammo so not much to complain about there. I would shoot this over any blazer/tula any day.
emt59 said:
You came through with ammo on hand when I was having trouble finding it. The ammo was competitively priced along all others.
SteveGun357 said:
Only one had a damged jacket. I didnt even load it in the magazine. The other 999 have fired perfectly. That is a 99.9% excellence record with me. Good deal. Could not believe how quickly you shipped.
MP 272 said:
Ordered the 1000 rounds - haven't shot any yet. It is clean and well made - great service! I have confidence enough to use it as personal carry! Thanks AmmoNet Dave - Sarasota
gasman said:
A little concerned about reloads, however my concerns soon vanished as the ammo performed flawlessly.
Vorbdad said:
Even though this ammo was reloads, we experienced maybe only two jams out of 500 or so rounds shot so far. My brother and I are very happy with our results. Will definitely buy some more.
Steve said:
I was impressed with the service from Ammo.com as well as the timeframe of delivery. The 40 cal MBI FMJ 180 gr. ammo looked good, fired flawlessly, and appears to be fairly clean doing it. I've only fired approximately 30 rds. through my Glock 23 gen 4 so far, but am satisfied with no jamming or ejection problems...would definitely consider in the future.
kwaddell said:
I needed decent target range rounds for my Glock 22. Even though these are reloads not a single round jammed. All of the rounds fired cleanly. We must have gone through 100 - 200 rounds at the range. Good price. Good rounds. Will definitely purchase again.

Alexander said:
No issue at all
Flyman said:
I have only fired about 35 rounds of this ammo so far, but it has performed just as well as some reloads I have. I fired it through a Browning HP, no misfires and accuracy was good.
Scott said:
Bought 500 rounds and have gone through approx. 200 and haven't had any issues. The one thing that bothered me slightly was 1 out of every 20 or so rounds was steel cased. It's not enough for me to knock it down a point in the review but it was advertised as "Brass" and it wasn't all brass.
Jas said:
Fired all 100 the first time out with 100% success. I didn't notice any difference from shot to shot like in some reloads. Every ejection was smooth and never had a hangup which is most important.
Top Shot said:
I went to the range and pumped 100 rounds out and no problems at all. Great value...
The Man said:
pumped 400 rounds through my hand gun with no problems. It was a good deal.
The Patriot said:
Used 200 rounds at the range without any problems, Great value.
The Big Man said:
Great value for everyday range shooting. No problems what so ever with every single round.

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.

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.

Excellent value in a monolithic projectile hollow-point format. Without detailed ballistic testing, I would say SB being a reputable manufacturer I have a long positive history with in my handguns, I expect these in .40 to perform quite well. Well packed, excellent quality components, shipped fast at a very competitive price!

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!!

Bullet Points: 40 Cal Ammo

A leading cartridge among the FBI and law enforcement agencies in the United States, the .40 Smith & Wesson gives police the capacity of the 9mm and the power of the .45 – also making it popular among civilians for self-defense and sport shooting.
.40 S&W ammo has also been adopted by the U.S. Coast Guard as its primary issue sidearm, due to its balance of muzzle energies and magazine capacity.
Civilians have adopted .40 S&W ammunition for many of the same reasons law enforcement has. Its mix of magazine capacity, muzzle energy and limited recoil make it ideal for home defense and concealed carry. Find .40 S&W ammo for sale in a variety of quantities and bullet types.
