History of Bulk 5.56 Ammo

  • gokart04 said:

    Finally got to shoot some of this the other day. Worked well and shot consistant/accurate. No feeding or fire failures out of about 100 rounds in my BCM AR-15. I feel the price is a bit too high at this time.

  • J.W. said:

    These were the first rounds shot through my ar. I have no complaints, it cycles fine even through rapid firing. I would definitely buy these again.

  • H.D. said:

    Works great, cycles fine, glad I found your sight.

  • Pat said:

    This is excellent ammo. Velocity is up there, at least in my 20" barrel DTI ar 15. Kinda lucky to buy this cheap ammo and get it to shoot the way this stuff did. I love being able to buy metal cases as well as brass cases. The metal are non-reloadable and it's nice to just shoot these and not worry about looking after shooting. I worry about the future of buying ammo over the 'net in the future. Here in Illinois our great governor Quinn moves on every front to close the avenues to get ammo. Good Shooting to All

  • Russell B said:

    I ordered 2000 rounds and two ammo boxes the 50 caliber larger ones. The ammo boxes were brand new as promised and no signs of rust, sand etc. simply new. The 1000 rounds of 556 filled it almost to the rim. We pleased and will be back.

  • Shooter McGee said:

    I searched many places for this product. You had the best price around, and the product arrived on schedule. Thanks for your great product and service.

  • Chris said:

    Not only is the price fantastic, but my shipment arrived in pristine condition. I was a new customer, and didn't know what to expect. I had a very bad experience buying ammunition on line from another place that claims to be 'cheaper than...ahem.. anything'. My experience with Ammo.com could not have been better. The trusted brand and quality of my order goes without saying. But the handling, packaging, and service from the people at Ammo.com was phenomenal, even surprising given the world we live in where poor service is pretty much expected. I will not shop anywhere else. Ammo.com is my go to supplier.

  • Tim said:

    Good price for ammo, not shinny but who cares its ment to shoot not to look at

  • Bobber1123 said:

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

  • Ron said:

    First time I used you guys and I'm impressed. Great prices,fast service. Keep up the good work.

  • 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.

  • Steven said:

    The Ammo performed great. Consistent groups and accuracy. I experienced zero failures in the 300 rounds I fired. I used the ammo in a 1/9 twist barrel and Zerroed and Primary Arms LPVO in just 12 rounds. Once zeroed my shots stayed withing the 300 meter silhouette center mass circle. I'm verry impresssd. I did know what to expect since I always use the higher grain green tip from winchester. Many say you need a 1/12 twist barrel to get good performance from this ammo; I disagree.

  • Fiftysum said:

    I just bought a Colt LE6920 5.65 caliber. The closest thing I ever shot was my M16 when I was in the Army during the Vietnam era -- a long time ago. So my review is not based on a comparison with any other ammo brand in this caliber. I bought Winchester because it is a known brand, is labeled for target use, and I feel it was available for a good price here on Ammo.com. I know there are some premium brands, which I will try eventually, and there are lots of brands I never heard of. Some of them may be good, I just don't know anything about them yet. I'm giving the Winchester 5.56 target ammo five stars in each category because my shots were consistently within one inch of the bullseye at 25 and 50 yards. That I hit the target at all at 100 yards I will count as okay because I didn't have a scope and I could just barely make out the 100-yard target with my not-so-good-as-when-I-was-20 eyesight. I qualified "sharpshooter" when I was in the Army, having missed "expert" by one shot. It makes me happy that this Colt M4 is as accurate, if not more so, than my Army M-16. Good ammo should give consistent results. This Winchester target brand delivers for me.

  • 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.

  • Blake said:

    Excellent ammo. Very accurate from the AR and bolt gun. Will be buying more.

  • Rysio said:

    Very good ammo although it is Russian. Performs as expected no problems.

  • 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.

  • 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.

  • John said:

    Outstanding job, I will use this company and tell my friends.

  • 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.

  • Mr honest...!! said:

    I used to 556 boat tail full metal jackets to practice and hone my skills...!! If and when I have to rely on my ammo to save my life , my 30 round mags will hold the Fiocchi fmghp brand in a 69 grain....!! Thank you Fiocchi for producing a superior quality of ammunition at a reasonable price...!! Sincerely Mr Honest P.S. I am a real person , a 50 year old single father with three daughters living at home... This is no BS review , I'm as real as you...!!

  • 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.

  • Bone Crusher said:

    Shoots straight, flying fast.

  • T-bag said:

    For the price and quality, never thought I'd be using green tips as target rounds. My AR hasn't jammed up yet after 100 rounds or so, which is impressive. My AR is very picky on ammo, usually can't get 30 rounds out without a couple jams. But this stuff runs like butter through my AR, with some impressive penetration to boot.

  • Mick said:

    All ammo went down range with consistent velocity and tight groupings. Previously purchased ammo from another party had poorly seated primers, this jamming my fire arm.

  • olbull 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.
