Customer Reviews

  • Bear Patrol said:

    Ammo comes in 5 plastic mini ammo boxes that look really neat! I wish the carry handles were real but they’re still worth holding onto for future use. So far I’ve put about 360 of these through my Windham HBC with no issues. As for accuracy I’ve only fired at targets from 100 yards or less from a standing position, so I’m not sure how they do at longer ranges but they always hit where I aim at those distances. The only downside for me so far is that I have to use paper targets or improvised targets (milk jugs, cans, etc.) Because these were leaving some SERIOUS dents in my 1/2 inch thick ar500 steel target. Overall I’d definitely recommend these to someone looking for decent 5.56 ammo at a good price.

  • Thomas said:

    Ran this ammo thru my Ruger AR with a Banish suppressor on, and everyone was amazed at how quiet it was, and when my target came back in, how accurate. Great ammo, would buy again.

  • Cam said:

    Ammo was cheap and works as designed

  • Ernest said:

    Great price good rounds straight A across the board

  • 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:

    Ammo was inexpensive and dependable. Shipping was on time. Would definitely recommend.

  • William said:

    I have had a chance to use a few of the rounds, and am happy with the performance. No jams, and true flight.

  • Lark said:

    I have went thru about 200 rounds so far. Tight groups and no problems whatsoever. I have been trying out different ammo for different AR's. I typically buy 1,000--2,000 rounds at a time. I try to keep the cost as close to 40 cents per round as I can get. This was 57.5 cents per round (but I wanted to give it a try). Again, nothing bad to say about this ammo--but the price will probably keep me from ordering more. Also--I prefer 62 grain (75 and 77 grain would be my top choices, but (usually) the cost is prohibitive). Very good ammo.

  • CM said:

    First time customer (of website and vendor), was really happy with their value, the way they shot and the quick arrival!

  • 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.

  • 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

  • Matthew said:

    The Ammo is great, but the one hitch in my "Giddy-up" is: The ammo on the website reads "FMJ-BT", but what showed up at my door was regular FMJ. I'll still shoot it, but I'll be wary, before I order from here.

  • Glen D said:

    Overall no jams after firing 120 rounds, good ammo at a fantasic price . perfect for the range good quality ammo, federal delivers!

  • patrick said:

    Great ammo

  • bcharles66 said:

  • Michael said:

    Fast delivery, ammo is nicely packed into small boxes. Definitely will order again!

  • JV said:

    As the title states it fired every time I pulled the trigger and I was satisfied with the grouping at 50 yards with just a Trijicon MRO. For range training ammo I wouldn't hesitate to order it again. Plus the shipping and order processing was very fast! All good.

  • David said:

    Performs well

  • Joe said:

    As far as the look and the function of the ammo I’m really pleased with it. The price met or was cheaper than competitors. They were packaged well and clean. They also fired great out of my AR. The thing that stood out the most was the fact that I made my purchase on July 3rd around noon and I received the ammo on July 4th before noon. I was so surprised! I will definitely be ordering here in the future.

  • Jim said:

    Worked great

  • Echelon 9 mm said:

    Very pleased with this ammo that I bought It looks to be well put together every round shot as it should I didn't have any jamming issues everything fed the way it should Good ammo I'll be buying it again.

  • DAVID said:

    Excellent service from when I placed my order to when I received it. I'll be ordering here from now on.

    Great Ammo; Pricey

  • J bone said:

    Same ammo as all the rest, most I've ever paid .

  • 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.

  • anthgrge said:

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

  • 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.

  • Doug said:

  • 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.

  • D. said:

    Was very happy with proformance of Winchester 556.no jams with 2 ARs.will be making another purchase very soon.Thanx much AMMO.you have great sales.

  • 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.
