Justis said:
I've used Winchester rounds in other calibers and never been disappointed by them, and I can say the same for these 5.56 rounds. Excellent training rounds, good pricing, and I've had no issues with the first 450 rounds I've used so far.

The rounds were dirty, with some having excess powder or some kind of processing oil/grease on them. A few boxes had 18/19 rounds in them. Worked well in my rifle after 500 rounds so far and were a good price.

Chris said:
I bought 500 rounds of the 556 FMJ out of the first few boxes (60 rounds) 11 have failed to fire. Firing pin struck the bullet but no boom. Will not be purchasing again.
-
Robert B said:
This Ammo shoots well, However when trying to reload the brass I broke 2 decapping pins in my sizing die. I cut the head off two cases and found the flash hole is off center. So even though the ammo shoots well it cannot be reloaded.
-
Signman said:
Jammed every other round. Very disappointed.
-
Def said:
This stuff is cheap, and I value that. The last 4 boxes I bought are super dirty and not polished like it is 40 year old military surplus. You can see the annealing, and it looks like it came out of an ammo can 40 yrs ago . The consistency is all over the place and I wonder why.
-
Jack said:
I have always put M193 as offensive/defensive ammo, which is why I purchased it in the first place. I tested 80 rounds at 25, 50, 100, and 300 yards with a Sig M400, it was dead on accurate.

Mike O said:
Shot this on my high end Geissele rifle and very, very happy with it ... target practice

Ranger5688 said:
Bullet strength and bullet placement are key factors,. I wouldn’t recommend all 223 for big buck deer,. Only a few will do the trick ,. It takes a powerful vital hit to bring a buck down,. The penetration and shock wave is what’s needed to take the game down ,. Choose your caliber wisely ,.

Cody said:
Best 62 gr round Ive used. I shoot a .223 Wylde barrel on a AR -15 used for matches. These perform close to as well as hand loads made for the rifle. I would use them for more than practicing anytime
-
Bru said:
It's Hornady Black. Goes down range well, gives decent groups at 50 & 100 Yards through a Hellion. It's not Match grade but it is consistent for my usage. Good prices and quick shipping is always a bonus too! Thanks Ammo.com

Sully said:
Great ammo, works great out of a new build, just have to try it out on the coyotes.

Jim said:
None

J-Mac said:
Very reliable ammo and consistent. A little on the pricey side but you get Hornady quality.

Zachary said:
Works great out of my 11.5" bcm and my 18" 1:8 twist barrel consistent groups and no issues.
