Customer Reviews

  • 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.

  • 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!

  • 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.

  • Richard said:

    No problems shooting from any of my ARs

  • Hank said:

    Fired 200 rounds and the ammo performed so far performed well.

  • Alan said:

    Product was shiped in a timely mannner was well packaged and performed perfectly

  • Carl said:

    Will be ordering more I am very satisfied with the delivery and price ammo shoots good

  • AZ SHOTGUN said:

    Great ammo for the price.

  • Nate said:

    The ammo itself LOOKS beautiful compared to Lake City penetrators but I have not shot it yet so I can't comment on that. I paid more per round, but that is just the market, not Ammo.com.

  • Bigthiss said:

    Great ammunition for the price. I used to buy the federal loose bulk ammo in 500 and 1000 but there were always at least 10-20 that were either faulty loads or misfired. This ammo is hands down the best for the price that I have purchased and shot. Highly recommend!!

    Man this ammo can in, in a matter of days nice quality

  • Freddy said:

    Better then I excepted. Quick delivery, at a great price. Not one fault. Will be using again in the future. Keep up the good work guys.

  • RUINED MY PISTOL said:

    I bought this ammo brand. It has ruined my barrel of my pistol!!!!!!!!!!

  • 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

  • beetle said:

    CANT GO WRONG WITH THIS AMMO

  • ammo said:

    remington did it again with another great ammo and ammo.com low price you can't bet it.

  • Freakazoid said:

    This ammo is very consistent. Bench firing my Sako .223 I can put three consecutive rounds in a nickle at 100 yds. Love this ammo!

  • Al said:

    As good as Federal and a lot less expensive.......Federal is supposed to be the Cadilac of ammo.....well, PMC is equal if not as good or even better.....I am a user from now on.

  • BonzoDRmc said:

    was my first purchase here, but WILL NOT be my last. great ammo and a even greater price. this seller is highly recomended. the ammo is top notch ammo. shoots clean and very acurate. like i said i WILL be getting more !!!
