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

  • Gabe said:

    I was looking for inexpensive practice ammo,and this was a good deal all around. Ammo was a good price relative to the times.Checkout was easy. Ammo was delivered quickly. Only had time for a100 rounds , no problems. Really like getting the ammo can too.

  • Matthew said:

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

  • Spencer said:

    Ran 600 so far with no issues.

  • LP said:

    Excellent price for the ammo, everything arrived quickly and packaged well. Ammo performed great at the range, making it yet another great day at the range!

  • Slap said:

    Arrived in 3 days, shoots just fine, the CAR-15 never missed a beat! Given the current supply issues even the price was better than most I've seen. Great job! Thank you I will be a repeat customer.

  • 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.

  • edward said:

    We fired over 300 rds on the range from 15 to 100 yards. The Black Hills 556 and 223 is absolutely the finest rifle ammo our agency ever used. It will save your life if ever in a gun battle with bad guys.

  • 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.

  • THL said:

    Took it out in my tavor, with a 14x primary arms scope, shoots about 2 MOA off of a bench in quick fire. Not too shabby for a HD OTM round rather than the match BTHP rounds

  • CM said:

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

  • Tim said:

    Military grade green tip ammo it has a steel core and is magnetic. perfectly annealed brass boxer primed reloadable cases. It is a bit pricey at $1.19 per round after shipping . So it's not for people with short pockets or shooting at worthless paper. These get stored with my zombie apocalypse or S.H.T.F ammo supply Would buy again just because you can never have too much ammo ????

  • 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

  • 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 ,.

  • 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.

  • 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.
