    Love the stripper clips. I think it took just 2 days to arrive. The price was excellent.

  • Randall11 said:

    Have shot a few hundred rounds not a single misfire. Shipping was quick too.

  • David said:

    I ordered this ammo on a Monday and it was at my door on Friday! Considering that it had to be shipped four states away that is FAST shipping. I also like the fact that Ammo.com donates a portion of every sale to pro gun institutions. This is now my number one "go to" source for ammo.

  • B said:

    Very fast delivery. Great quality. Thank you!

  • Whistle-Pig said:

    I hand load 55g blitzing for my AR and these performed exactly like my hand loads no adjustment in windage or elevation was needed. Although I didn't have time to run them through the chronograph with the performance at 100 yards I'd say the advertised velocity is spot on with a 24 inch barrel.

  • 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.

  • Jetson said:

    Goes bang, burns clean, shoots straight no ftf’s or any other issues. I’d trust my life to it. Gonna get more.

  • 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.

  • Dave said:

    Compared to brass prices you cant beat it! Shot about 500 rounds between two weekends had no issues every round shot flawlessly I will be returning for more

  • Capt AR said:

    Spent 30 rounds @ 100 yrs.Fired prefect and only a couple off Mark.

  • Cameron said:

    Great shipping shoot fine at 100 yards could drill dime every shot

  • Spencer said:

    Ran 600 so far with no issues.

  • 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.

  • Chief said:

    Performed well. Lots of rounds and no issues!!

  • Rob said:

    It was a good ammo. Fired and help itself well on the 100, 200, and 300 ranges.

  • John said:

    Cost of steel cased ammo - cons of steel cased ammo - but well made AFAICT

  • 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.

  • Jamms said:

    Price was pretty good. But constant jamming and feeding issues in all 3 of our weapons. Casings seem soft. Not sure about that though. They did stay in decent groupings on the target at 50 yards. Oh and the damn boxes all came apart, had to just dump em all into a bucket. Frustrating because I like to just take one or two boxes to the range. But anyway.

  • 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.

  • JRL said:

    I got 1000 rounds of this. Just shot it today and it consistently chronos 100fps slower than advertised. NOT HAPPY AT ALL. Order another brand if you want full power ammo.
