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.

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.
-
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.

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.

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.

Nikonsal said:
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.

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.
-
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.
-
Otis said:
value, quality and performance was as well as expected for the costs.
-
Jody said:
I would recommend this ammo to anyone having a .40 S & W pistol..I used in my new Taurus TU pistol
-
Adam said:
I fired these rounds using my mp 40. I will definitely use these again.
-
Dean said:
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.
-
Steve said:
Ammo seemed to work well . It was shipped on time and we are very happy with it. We will order again along with some .45acp when you have it available
-
Bud said:
Great price and quick delivery. All is good, no issues.
-
Jersy said:

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.
