  • 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.

  • B.S said:

  • 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!!

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

  • 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

  • Head hunter said:

    Shoots amazing accurate and plenty of knock down power for plucking down rodents such as ground hogs . You can reach out and touch something with accuracy and confidence .

  • Matthew said:

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

  • 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.

  • 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:

  • 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

  • Greg said:

    Exactly what I needed. Now I just have to learn how to fire the weapon.

  • Dave said:

    Great ammo for coyotes Local stores don't carry 40 grain anymore I will buy from your company for other ammo when my stocks get low

  • 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 ,.

  • Cody said:

    Best 62 gr round Ive used. I shoot a .223 Wylde barrel on a AR -15 used for matches. These perform close to as well as hand loads made for the rifle. I would use them for more than practicing anytime

  • Joe said:

    Really good on the range. haven't had a problem yet

  • Larry said:

    good ammo at an excellent price

    This is a quality bullet

  • Voltron said:

    Good product, great price, packaged well, arrived on time, shoots well, will purchase again Works fine in my suppressed DDM4 V7

  • Jimmy Crack Corn said:

    Seemed good once I had ar sighted in red dot at 40yds. New ar prolly like 20rds (mostly newbie errors well say). once zeroed blew throught 200rds no hiccups n could rapid fire on target well unless bullet accounted for my terrible aim?

  • Mike said:

    Best prices came within a few days of ordering. Very happy, would recommend and use again and again.

  • Michael said:

    The price is one of lowest price per bullet I've found. The quality and performance are great. I've shot over 200 rounds of these and not a single misfire or dud. You can't go wrong with these for your AR

  • Eric said:

    I bought the PMC 55.6 ammo and I have had issues every time I am at the range with at least 1 to 3 misfires per 30 round clip. I am shooting with a BCM 16 inch Rifle that was just bought a few months ago and only has about 200 rounds through it. I took it apart and cleaned the rifle and still have misfires and have used multiple different clips.

  • Hamb0ne10 said:

    Never had a problem with pmc ammo.

  • J said:

    Quality ammunition

  • Josh said:

    Had two days of rifle training scheduled with a paid group. Both training classes cost around $1,000 for both days so the issue is when you pay for training you need ammo that will perform so that way you don't have to worry about missing out on what you've already paid for and this ammo did that! Not one misfire out of every round of the thousand purchased. Nice to be able to still find quality products out here.

  • Kyle said:

    I've used about 200 rounds and it works flawlessly.

  • Just a guy ~ said:

    This is my favorite 5.56 cartridge, hands down. Every component is top quality & PMC doesn’t cut corners. I’ve shot them all and this is the most accurate & reliable 5.56 factory cartridge. I prefer the 193 - wish it was 62 or 69 grains… The brass is excellent & should absolutely be kept for reloads (I safely get 3 reloads per). A small shop by me sells it for $8.99 a box in 2023… That’s a steal. Have fun & remember that firearms safety is 100% on us.

  • Ron said:

    I like PMC Ammo the 5.56X45mmNato is what I shoot. Great for range, self protection, The reason I purchased this ammo is because of who makes this.

  • Kenneth said:

    couldnt find ammo locally so i checked the net fully expecting 2-3 wks for delivery. ordered early on a saturday morning. was on my door step monday. impressive

  • txweld said:

    All good

  • Runner said:

    PMC is a very reliable ammunition , I would not hesitate to use if for self defense. It shot well and now that I have shot it and used it all, I`ll need to order more. BTW , I use PMC in my handgun for home protection and it is as good as it gets and the 5.56x45 is as great .

  • MM said:

    I shot about 200 rounds through my brand new SIG716. The very first 3-4 rounds wouldn't feed perfectly, but I attribute this to the brand spanking new equipment. After that, rifle and ammo performed flawlessly. Not a single issue with feeding, cycling, firing, etc. At 150 yards, I had all shots within about 2-3 inches using a cheap scope and no rest. Great product and especially GREAT SERVICE! Thank you guys!!!

  • D said:

    Great customer service, placed the order last friday fully expecting not to get the order with all that is going on, you won't find a better company to deal with, as for the Ammo, top notch perfect for my use.

  • CowwFace said:

    I got this for taking to the range, went through about 100 rounds and zero duds. works perfectly in 2 AR's. We were using Red-Dot scopes, and hit what we were aiming at about 100 yrds away. I would highly recommend this ammo.
