Christian said:
Shot 100 rounds through my new AR-15 and everything was flawless. Very happy with the service, delivery time and quality of the Ammo.
-
Matthew said:

Bob said:

Rob said:
It was a good ammo. Fired and help itself well on the 100, 200, and 300 ranges.
-
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.
-
Signman said:
Jammed every other round. Very disappointed.
-
JayG said:
I've been using Tula in my XDM .45 for plinking and have had no issues so I thought I'd give these a try, but the Tula .223 Rem 55gr malfunctions VERY often in my modern sporting rifle. Every 2-4 rounds caused a failure to eject/cycle, or double feed. I've had NO issues with brass in the same rifle. Not worth the pennies saved, I won't be buying Tula .223 again or even finishing the rounds I bought.

Subtle and accurate aim and shot , great point of contact at the target. Very effective at the range.

MrDreamer79 said:
Zero issue with this rounds performance, even with my limited rifle experience I was able to get 1 MOA accuracy out of my AR15 style rifle.
-
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.
-
RONALD said:
No surprise here but the price per round shows as 63.8 cents. With shipping and sales tax, that easily went to about 85 cents. I did receive it in a timely fashion and it was well-padded in a cardboard box but would have preferred different packing from the factory. My error. A range pack means loose rounds inside a box. The ammo itself is so-so for its intended purpose. I also purchased Belom 7.62x39 (no longer available here) and cannot address ammo quality yet, but the factory packaging (20 rounds per PLASTIC case) was phenomenal.

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.

Jacob said:
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.
