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.
-
scot said:
after about 250 rounds no problems at all, will be getting some more soon.
-
Doctor said:
See summary. Good quality overall.

Received ammo in 2 days. Shot 400 rounds first day with no issues what so ever. Have shot a total 750 rounds so far with zero problems with ammo. Great value.
-
Ed said:
I was very surprised at the speed of delivery, received my ammo 2 days after placing the order. Went to the range week later and put 200 rounds down range. No miss fires, jambs or fly always. Great service, great ammo.
-
Mac said:
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.

BMan said:
Went through 150 rounds of this to try it out. No misfires or jams, accurate, and no ricochets that I could tell
-
Bob said:
Quality seem to be top notch. I had no problems with the ammo at all. Fired cleanly. A real bargain.

no fail to feed no misfires, no nothing very enjoyable to shoot when there no HICCUPS

iolhippie said:
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.

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.

Rich said:
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!!

Steve said:
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.
