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.

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.

Went through 150 rounds of this to try it out. No misfires or jams, accurate, and no ricochets that I could tell

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.

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

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.

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.

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!!

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.
