Not sure if those of us with bad reviews just hit a bad batch, but I too was unable to use this ammo. STG-556 cycled ok for the first couple mags, but never held bolt back on last. Once the gun heated up it short stroked every round. Even on the "dirty" piston setting it was a single shot gun. I have about 1.5k of various other .223 and 5.56 through the gun with ZERO malfunctions. LMT PISTON MRP. Short stroked EVERY round. I have about 300 rounds of other .223 and 5.56 through the gun with zero malfunctions. There must be something else going on with the ammo I got (and that some other reviewers got) because my issues were NOT gun related. I have not tried this ammo in a DI gun as of yet.

This ammunition is a very good value compared to the Lake City stuff, however, performance was not as consistent. My accurized Colt H-Bar that typically holds under 1MOA with Lake City M855 was shooting closer to 2MOA with this stuff. One thing I noticed is that the green coating used on the tips was very inconsistent...leaving blunt ends, irregular lengths, and sometimes a crooked tip. I did remove the thick coating off a few rounds and these did group markedly better. Despite this gripe, it's still great plinking ammo and functioned flawlessly in my rifle.

I bought 600 rds of this m855 ammo & didn't have a problem with the 1st 30 rd mag last Saturday, but the 2nd 30 rd mag single fed until about the last 5 rds. To rule out the mag. I loaded it with some different ammo & it fed just fine. We probably shot 250 rds most of which was other various ammo., all with no problems. I'm shooting a Bushmaster M4 that's about a year old with maybe 500 rds through it. It was clean at the start of our plinking session. I don't want to totally blame the ammo at this point, but it's sure looking suspicious. A marine friend was with me so for grins I had him clean the gun as he was taught. I'll see how it does the next time I get a chance to shoot probably after the holidays.

Save yourself loads of aggravation. Spend the money and buy a Bushmaster with 1:7 twist. My M4 is four years old and has cycled somewhere in the range of 50,000 rounds. I'm a class 3 shooter and it eats these bullets as fast as I can lock the mags. The only problem I ever had was a broken ejector from shooting steel-cased Wolf ammo. Replaced the broken ejector and was back on the firing line in minutes. Bushmaster's are voracious. They eat anything and everything. It's the gun you can bet your life on!

Excellent surplus ammo! All the Igmann M855 ammo fired (over 400 rounds so far)through my LWRC M6-A2 functioned flawlessly. I was pleased with the accuracy as well.

Please read the article on rifle twist. Thank You.

I'll tell you all this... this ammo was made for a mil spec rifle so all you RRA, Armalites, DPMS, etc. ain't gonna handle it. Get a real mil spec rifle and you can fire all day. Oh and I'm Colt certified and military approved.

I purchased two cans of this ammo. It is defective ammo. The bad ammo appears to be concentrated in the same boxes. Most boxes function just fine however, a bad box can have as many as 15 out of thirty rounds that "short stroke". Either the powered is bad or there is not enough powder to cycle the bolt. This is target ammo only.

100 test rounds, and no problems. Pierced 1/2 " steal plate as well, at 50 yards. Your guns must have a problem if they do not work well for you.

I have a M4 type Bushmaster that I have put approximately 30,000+ rounds through. I have replaced just about everything on the gun, including the 16" barrel with a 20", heavy stainless steel competition one that is extremely accurate. I have shot many types of rounds through this gun, but these really impressed me. I performed accuracy test at 100 and 200 yards, versus standard Remington FMJ. I shot better groups with these. I then performed penetration tests on 1/4" and 1/2" steel plates I bought from a metal scrap yard. They penetrated the 1/4" plate like paper, and then the same on the 1/2" plate at 50 yards. These were not little holes either. They were approximately the size of a 38 special bullet. Out of 100 rounds tested, I did not have a single problem. If you had any problems with this ammo, something is wrong with your weapon.

This is good quality ammo. Exact same that I've shot on military ranges for years. Its not always shiny... but it will get the job done. If your an military guy or gal... this is exactly what your used to shooting on the range. If you ever ended up in a ammo shack you know.

I have a custom Colt AR-15 chambered for 5.56 with a 20" heavy barrel 1/9 twist. Never had any problems with any M855 or M193 ammo before. From surplus to commercial this weapon has been rock solid and reliable. I thought I would give this stuff a test first before making any large purchases, after reading some of the reviews. Face it folks, NATO rejected it for a reason. I experienced two to three short strokes and jams per 20 round mag. I also felt the ammo seemed very weak as far as recoil and crack. Definately the weakest ammo I shot that day and the only one I had a problem with. The bottom line is "DONT BET YOUR LIFE ON IT"

I recently bought a microtech STG 556( an american AUG). I wasn't able to fire 3 rounds with out the Ammo not properly feeding or straight up jamming. I know i wasn't using an AR15 like everybody else, but it looked to me as though since they said it was too slow for NATO, it doesn't produce enough gas to cycle my STG 556. I will try the Ammo out in a friends AR15 since i have over 250 rounds of it left out of a box of 300 and maybe the gun will make a difference. One must be careful with military surplus ammo.

listen up guys if your AR15 doesn't have a 5.56 NATO chamber or the like don't bother. You're not reading your owners manuals or you aren't reading up on your ammo specs ... .223 chambers don't cut it for this ammo. If you want an AR15 that can handle this stuff look to COLT or DPMS and a few others otherwise your shooting a rifle that cant handle the real deal. This is a fact. Now a 1:7 barrel twist is going to shoot this stuff the way its meant to be shot...1:9 decent as well. Truth is its made for the 1:7 with a 5.56 chamber anything else and the results might get sketchy. If you bought an AR15 with the .223 chamber I highly suggest you go out and buy the 'real thing' if you want positive results with miltary 885.

This is great ammo for the M4 and newer ar15s. 1in9 or 1in7 twist barrels function this stuff excellent. If you use a rifle geared for m193 type ammo aka 1in 12 twist barrel then you will have short stroking problems as well as poor accuracy. To everyone who complains of bad functioning please make sure your weapon is made for this ss109 ammo. Otherwise stick with m193. Happy Shooting!!

Reading the reviews of this ammo jamming leads me to ask 2 questions. 1) What type of garbage gun are you using, and is it in proper working order? (Assembled correctly & Cleaned). 2) What OTHER ammo does your gun jam on (cause if it jams on A LOT then its probably your RIFLE and NOT the ammo). I bought 1000 of these suckers, loaded up my Bushmaster AR-15 and took it to the woods. LOTS OF JAMS, WOW, I was mad, then I went back and looked at my rifle, the GAS BLOCK was improperly installed (never go back to that gunsmith), so after checking to make sure EVERYTHING on the rifle was correct I went back out and shot over 100 rounds on Semi Auto Fire (as fast as I could pull the trigger) and NOT ONE LOCKUP. I have to state this again, please CHECK YOUR RIFLE before complaining that something doesn't work, this ammo works JUST FINE. I'm not a EXPERT by any stretch of the imagination, so If I can figure it out, you should too.

I fired this ammo thru a heavy barrel Bushmaster 20 inch barrel into a section of railroad steel track I had. IT BLEW A 38CAL. HOLE THRU ALMOST 1/2 INCH STEEL LIKE IT WAS BUTTER !!!!! Good stuff if you need ammo that will do this.

It's about all I have shot through my mini 14 and I have been pleased w/it. No problems at all 600 rnds or so. A buddy of mine was hitting a 12" piece of card board at 200yrds his 1st time shooting my rifle. All the negative reviews must B due to cheap rifles or dirty gas tubes,clean your guns people or get a better one. I'm gonna buy more. Like a guy w/an AR said,My gun eats it like candy!

This ammo works well in an AR with a 5.56X45 chambering. The internal dimensions of a 5.56X45 NATO is different than a 223. Remington SAAMI chambering. Military cases are made from thicker brass than commercial cases, which reduces the powder capacity and the NATO specification allows a higher chamber pressure. Most of the differences will effect accuracy. The SAMMI chamber has a longer leade. Which can cause the round to be unstable in flight, cause excessive wear to the bore where the leade meets the lands and groves and cause unstable pressures in the chamber. Do to the pressure related problems, it may cause problems in the gas system. In reloading these cases, it is unsafe to use the loading tables for a SAAMI round. With the dimensions being less as they are NATO Spec, this can cause a serious over pressure problem.

i just recently purchased a dpms and the guys thought it would be a good idea to buy some of this stuff .now ive red all the all the reviews and i know everybody has an opinion and thats fine . but heres the deal if you dont pay attention to what your gun feeds then your gonna get all kinds of jams and misfires . if your gun is a 223 and you try to shoot a 5.56 well thats like puttin a chainsaw spark plug in a car and thinkin its gonna run like a top.(aint gonna happen) They send owner manuals for a reason.Now im no expert but this is what i know. I spend alot of time in the scub shootin and i havnt had ANY problems with these and i have shot thousands of them ive sighted 4 scopes and to lasers in on these with no problems what so ever and thats with no cleaning for weeks on end. i do lots of youty hunting and although not the best bullet for the job im puttin them down at 300 to 500 yards away with 3 to 7 inch drop so it cant be all that bad besides if you dont like these prices go to your nearest gun shop and check out what there going for in the real world...Oh by the way these things are going through half inch steel 50 to hundred yards away concrete sinder blocks five at a time at shorter ranger .Put it this way if you gotta stop a car in the near future two or three in the block will do the trick. YALL HAVE A GREAT LIFE

BEFORE YOU BUY MAKE SURE YOUR AR CAN TAKE A 5.56

Read other reviews. This ammo is great. I have had no problems with my two M4s. It cycles well and is accurate. The cause for the misfires and feeds may be anything. Don't give up on the ammo. Tweek your weapons with a good reputable smith and try again. This ammo is too good to let go.

I have run about 200 round through my CAR-15 Bushy and my Mforgery. This stuff runs flawlessly in my rifles.

I was using a LWRC gas piston rifle and shot various different ammo at various grains. None of the other rounds experienced problems at all that day. The grains were 55, 62, 75, and 77. The manufacturers were Wolf, Sellior and Belliot, Federal, the mentioned igman, and 2 others I can't remember right now. Could be I got 2 bad cans, could be I just got a bad batch. I don't know. But the numbers are there for you for the ones that did get stuck. Will I buy the igman again? Maybe. The cans are nice. I'll have to caliper each round before I use it if I decide to do so though. Not sure 30 cents a round is worth that. Also, the 1200 rounds of igman were shot through a 3 month period after cleaning the rifle after each range day. Cleaned, inspected, and repeat problems. Not saying all the ammo is bad, just some of the rounds I received.

You guys who are complaining that the round won't cycle your bolt completely - try several ammo weights to see if it is the rifle. One likely cause of your rifle not cycling and/or double feeding is the two hex nuts that attach the gas tube fitting to the top of your bolt carrier. If they are a little bit loose, your rifle won't cycle correctly. This causes a double feed because the bolt comes back far enough to catch the next round, but not far enough to eject the shell just fired. If you are having double feeds, a second likely problem is a worn out magazine where the top has splayed apart a little bit. A decent rifle for any purpose other than match should shoot whatever you put in it, even shitty ammo. Hope it helps. - Joe

Out of the 1200 rounds I bought, I'd say about 20 percent of the rounds caused my rifle to double feed. I calipered the rounds that stuck to my bolt and they measured at .3775 while the other rounds measured lower than that averaging around .375. If you buy this stuff, don't count your life on it. and if you have to, caliper each round before you use it. Well atleast the cans they come in are nice. Hopefully they dont use lead based paint.

However this IS military ammo.It is not to nato specs.I'm not saying it's bad ammo,to me there's NO bad ammo.It does penetrate well and does fire well.BTY-get ALL the ammo you can before 1-JAN-08 because it's going sky high.Get it NOW!

FOR YOU GUYS THAT RATE THIS AMMO AS HAVING TO USE YOUR RIFLE AS A BOLT ACTION YOU DEFINITELY NEED TO 1. LEARN HOW TO USE YOUR RIFLE AND MAKE ADJUSTMENTS TO IT 2 OR SEND IT TO A GUNSMITH. THIS AMMO FEEDS AND FIRES LIKE A CHARM IN A GOOD AND WELL TUNED AR. SO MANY VARIABLES FROM CRAP MAGAZINES TO JUST PLAIN CRAP "FRANKENGUN" BUILDS THAT CAUSE MORE PROBLEMS THAN ANY AMMO OUT THERE. SO PLEASE SEND ME ALL YOUR WORTHLESS AMMO, I'LL SHOOT IT FOR YOU.

Definitly decent ammo. I was just looking for something to shoot so me and a couple friends went intogether and about around 4000 rounds. I have a bushmaster AR15 A2 and a DPMS M4 and a POF lower armalite floating upper. I have shot over a 3500 rounds and atleast 1000 of the this stuff through the Bushy with one jam total using the M855 after maybe 500 rounds in a couple days without cleaning. I would say depending on the twist this can be fairly acurate as well. First time using this @ 300 yards I got an 8'' group out with 20 rounds usuing iron sights. I like this for 1in 7 and even 1 in 9 twist.

I've put a few hundred of these through a Kel Tec SU 16C and a Anvil Arms M-4. No Problems.

I Purchased this ammo based on mixed reviews. Found that the ammo will not cycle chamber. This is a BAD AMMO do not purchase. I was firing an Armalite AR-15 well maintained. You will have to pull your charging handle after each round to Cycle ammo from mag. You will have to reload this ammo for it to be usable. : - (

i have experienced the m855 penetrator rounds first hand. i didnt buy them here but i use them quite often. i am a Marine and we use the m-16a4 and the m855 was designed for a rifle with a 1/7 twist like the m-16a2. you arent going to ge reliable feeding in an ar-15 unless it was previous govt issue. the ammo was produced to be used in a military rifle. i have not had a jam yet in the oh...1200 rounds i have used in either my m-16a4 service rifle or the 249 saw. so quit complaining.

I put 20 rounds through my Bushmaster AR, semi-rapid fire no problems. As far as penetration goes, I cannot say, I was just shooting paper at 50yds.

This ammo will work great if your gun is chambered to accept a 5.56 and .223 or the throat is eroded from a .223 chambering. The problem guns below sound like classic examples of what happens when you use 5.56 in a .223 only gun. Higher operating pressures and thicker case brass will result in jams and broken extractors! Everyone else - have a ball!

great stuff. bushmaster eats it like candy. negative people must have problem guns. Don't buy it so I can buy more.

out of a friends ar-15 it wouldnt even shoot, the 2 times he tried the bullet got jammed in his chamber and had to be banged out with a rifle rod, not sure whats up with that... but in my mini 14 it had no problems at all it was accurate, went bang when i pulled the trigger and had no problems ejecting which was interesting because my mini wont eat wolf, 1 out of every 3-5 rounds wont eject, so go figure, maybe this stuff aint the best for ARs but with a mini 14 it was great (its also a penetrator round has a steel core good stuff to have around;)

This stuff is great! You could have got it back in Jan for $227 a can right here! There are some old catalogs that say "If you want two cans in the original wooden crate, order two cans" this is not true! You just get a credit of $10 for the crate. 12 FPS to slow, some of the new AR15s dont like it. In my Mini14 works great.

I agree with ar4life, mrktdmon & Dave. I just fired 100 rounds, and NOT one missfire. all on target... Very good ammo, wourth the price. Thank's to Dud & indycory, You made me waste 100 Rds of good ammo, Maybe a couple of us need to work on our firearm's..

I shot 400 rounds of this today thru an old truck engine that was out in the desert. This ammo worked splendidly in my custom heavy barreled A2 that I just built. I should have ordered this back when it was only $299.00 a case.

I agree with ar4life, good thing I didn't listen to the other reviews. The ammo worked perfectly.

Glad I didn't read the reviews- or I may not have ordered any of this ammo. I've shot 1/2 case so far, out of 4 different AR's. Had 100% function in everything except my varmint AR (has a match chamber). I was just fooling around when I tried it in the varmint rifle, I wouldn't use SS109 in this rifle anyway, but the chamber was too tight to be reliable. But in all my M4's and A2. it was great, and accuracy was also good in the 7 twist barrels.

Alot of people do not know this ammo is produced in Serbia.A freind of mine purchased some and it did ok if u like to fire your ar like a bolt action.Read the flier carefully-{from the ctd magzine}.Was to slow for nato approval.Fart says what?

These things are junk, I cant believe I spent $300 on them. multiple misloads on every magazine in 2 new ar-15s They are apparentely not strong enough to comletely cycle the action. they made my ar-15 a "bolt action" A definite Don't Buy.
