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.

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!

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.

Great ammo. No problems what so ever after firing 200 rounds. Good price and super quick ship.

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.

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.

Walt said:
It was easy to order and had no problems comparing products. The package was heavy but taped and secured well. It arrived in the normal amount of time and performed well at the range. Good value.
-
Gomar cools said:
Good round and a value at the price point. Rounds ramp well in all makes of gun we use.

Todd said:
Its been great ammo. Will buy again.

Kam said:
Great
-
Bull said:
No jams, zero feed issues. Shoots clean . 4 star for performance was only due to it being 40 target ammo and the grouping wandered about 1/2 inch up or down. Over all was still in the mass zone at 21 and at 30 feet .
-
Joel said:
Ammo would look better if the aluminum casing was replaced with brass.
-
Kushlover said:
This round almost has to much powder. Looking at a spent cartridge the primer firing pin mark is almost pushed back out.
-
Jim said:
Very clean burning, little or no residue on gun
-
Steiny said:
I had been hoping for prices to drop before I ran out of my existing supply but that wasn't happening. Then I ran across ammo.com and found these. I'd never had any of this brand before but I'm quite satisfied with the product and ammo.com. All my future purchases will be through ammo.com.

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.

Perfect!!

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

The 40 Cal performed well no problems. The price was not bad, but i wish it cost less.

Donnie said:
I am a firm believer in Blazer Brass 40 S&W. I've never experienced a jam thru my Glock 23 with this ammo and it is a very clean shooting bullet. Plus excellent service as always from Ammo.Com. Ordered on Monday, entire order here on Tuesday!!!! Thank You
-
Ross said:
I've used this ammo for the last few months. I've put over 1000 rounds down range and haven't had any issues. Perfect for the range.
-
Mike said:
Top shelf ammo for the price. 125 rounds without a hiccup. Might want to consider a lighter round in a compact...kicked too much for my wife in my sr40c (usp handled it like a champ) but I wouldn't hesitate to buy again. Maybe 165gr so we can both use it :)
-
Donnie said:
Went thru 250 rounds over the last 2 weeks with no issues at all. Great ammo and very good price. Gun was a lot cleaner than I anticipated after I shot 130 rounds. Would recommend this ammo to anyone.
-
Lou said:
Good ammo for the price

Davedee said:
I use CCI as my preferred ammo. Have a fussy SIG 22 semi-auto that can only use CCI products. I have no issues with CCI in my other 40 and 9 mm cal. weapons and recommend to others. Also, I share with others when I purchase in bulk so they have an opportunity to try you out.

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.

Mike said:
I have never had any type of problem with Sellier & Bellot ammunition. It has always functioned exactly as it should.
-
Capt. Miller said:
We use these to qualify our department so we go through hundreds of rounds. This stuff barely dirty's the gun and has not misfired or jammed yet.
-
Gene said:
When you pull the trigger the ammo goes "bang!" What more can you ask? It burns clear, leaving gun fairly free of residues and carbon.
-
Bene said:
Bought 4 boxes. cycled flawlessly thru my Glock. Excellent value.
-
JoelDug said:
What is there to say... Sellier and Bellot is great ammo. What is not to like? This ammo alway fires well.

Great price and quick delivery. All is good, no issues.

It did not cycle too well. 5 duds.

Bud said:
Greta product! A little expensive per shell, but when shells can't be purchased locally, I suppose the additional is expected. Still can't find all caliber ammo, even at ammo.com.

I have only shot about 150 rnds through the gun, and the only hiccup was a few jammings that I believe were caused by an off brand 25 rnd. capacity clip.
