40 Cal (S&W) Ammo For Sale
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.

Went to the range and shot over 250 rounds from my Walther PPQ40. Not a single jam or misfire. Will definitely buy more!

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.

You came through with ammo on hand when I was having trouble finding it. The ammo was competitively priced along all others.

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.

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

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.
-
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:

Used 200 rounds at the range without any problems, Great value.

Great value for everyday range shooting. No problems what so ever with every single round.

Alan said:
I've ordered this ammo twice now. 1000 rounds each time. First 1000 went through my glock 23 without any failures of any kind. I'm onto the second 1000 now and anticipate the same flawless performance. Service is excellent. Shipping was very fast. Value is great.

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.

ALL ROCK said:
IS A GOOD AMMO I WENT INTO 150 ROUNDs EACH WITH MY GLOCK 23 GEN 4 .40 WITH NO PROBLEM AND I USE MY BERETTA 96 A1 WITH ANOTHER 150 WITH THE SAME AMMO, GOOD STUFF.

Jammed in both Glock 23 and S&W M&P. Failed to eject. First time this has happened in years.

Tyler said:
Works well enough, only had a few malfunctions in 1000 rounds shot. My big gripe is that the jackets separate from the lead core as the bullet leaves your muzzle. This does seem to be widespread on the forums that I have read. Blazer has even responded via email and acknowledged that this does happen, something related to cost savings in the manufacture process to ensure cheaper prices for the end consumer. They say there is no risk of damage to your firearm, and I have no reason not to believe that. but there is a risk if you are using Blazer ammo in live-fire training exercises, where other students might be within close proximity. some instructors have even banned the use of Blazer ammo in their training classes. So basically it is a great cheap range ammo, if you don't mind the occasional speckling of copper bits on your targets. just don't use it for live fire training exercises where you are within close proximity to other people.

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.

This round almost has to much powder. Looking at a spent cartridge the primer firing pin mark is almost pushed back out.

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!!

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.

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

mikentexas said:
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.
-
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.
