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.

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'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.

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.
