Late afternoon, 55 degrees, great late fall day in Maine. Shot approx 150 rds dated 99. I used a Colt pre ban sporter 2 with a 1/7 twist, 20" Barrel and a self built RRA 16" 1/9 upper on a Stag arms lower with an A1 buttstock. I had one FTF. The primer showed a shallow dent. I later fed the round by hand and it did fire. The boom for all rounds seemed unusually loud, but other than the one FTF all other rounds worked good. Shot very nice groupd for my 50yd zero. The FTF was with the RRA. I collected the fired rounds and looked at the primer area. All seemed normal, no signs of excessive pressure.

Finally had time to run a couple hundred through the M16. Specs:
DPMS chrome lined M4 with barrel cut down to 12.5" Colt FA bolt/carrier and RDIAS Gun is properly headspaced and timed 200 rounds fired in SA & FA with no problems or signs of high pressure. I reiterate that I am willing to buy this from anyone who finds it doesn't work with their gun, just drop me a PM or e-mail. |

I bought 3 boxes at a range when I ran out of XM193. Within the first 15 rounds I had a fail to fire. I pulled the charging handle and looked at the round. It had the primer from the previous round stuck to the back of it. The previous round had fired, the primer stuck to the firing pin, then became stuck to the back of the next round to chamber. The primer on the round that did not fire had never been touched. I was using an M4gery built on a DPMS lower, RRA upper, RRA bolt and carrier, CMMG inc. barrel. I have fired around 1500 rounds from it and this was the first time a round has not fired. I typically shoot XM193 or Black hills 55gr.

How the hell does this happen? I've fired a few hundred rounds from a Colt 20" Gov't model without a single problem. And after reading all these negative reports, I've taken to collecting all my brass and checking them. No blown primers, signs of excessive pressure, nothing.
I have found a handful of 'rejects' I've put aside consisting of badly dented cases and split necks, but I always eyeball surplus ammo, so no big deal there. |

I fired 200 rounds of this from my Armalite M15A4 (20" barrel) and another 200 from my Olympic OA98 pistol with no problems - no blown primers, no split necks. BTW, I've had split necks on MX855 before. I would buy again at this price, due to excellent accuracy and lack of problems with my guns.

I have fired around 800 rounds through my pre ban Colt A2 20", My BM 16" and BM 14 1/2" all with no problems. Good thing because I bought 6k rounds of this when it first hit the market. I am quite satisfied.

Went through around forty rounds today with my Bushmaster lower / Model 1 Parts 16" M4-ish upper. Blown primers every third round or so. A friend was using the same ammuntion, same lot, everything, through his Bushmaster Disappator setup, no problems at all.
This leads me to ask, can blown primers be partially a result of the ammunition AND the rifle? BTW, had to stop for the day when one of the primers ended up in the cam key recess, jamming up the works bad enough for me to do some surgery on the rifle. A frustrating thing, but nothing a little time couldn't repair. |

Fired 100 rounds in one hour, 1/9 20". No problems of any type, slightly less accurate than XM193, more accurate than Wolf 62gr poly.

Bought 80 rounds just to test the ammo, and had one round with a messed up neck. I pulled that round, and found a lot more neck sealant then i'd find with LC stuff, but about the same amount as RORG (bristish ammo).
Put 79 rounds through the rifle, all went boom, and I had no issues with the ammo. I will probably buy this stuff in bulk eventually. |

I've put 200 rds. down range. So far I've had one blown primer. Ammo isn't all that accurate, but that could be the loose nut on the trigger (me). Q3131 gives better results for me. I might buy again. Rifle = RRA with a 16" barrel.

1000 rounds now, not a single problem.
Only about 10 rounds that seemed a bit questionable as far as dents go, and only 1 that I would not run through my rifle -- the end of the casing with the bullet was severely bent and it would be impossible to even get it to feed. I got in 2,000 more rounds last week and this brass looks even better than my last order :-) No blown primers. Ben |

Yes. A tight chamber/throat will increase case pressures leading to a higher chance that some of that pressure will be used to push out the primer. I will make a wild guess and say that the Model 1 barrel may have a sammi spec chamber whereas the BM has a nato spec one. Gas tube length and/or gas port diameter could also be factor here as well. |

Well those things happen. I put 240 rounds of this through my stag limited upper today with no real problems. I was shooting ADCOM, WWB, Wolf and Black Hills Blue Box. I had some FTF with all ammo but being new to AR's I think I or my mags were the problem. 240 rounds of ADCOM, 240 rounds of WWB and 120 of Wolf. I picked up the casings from all ammo and the ADCOM showed no signs of excessive pressure in my gun. Zero blown primers. I have no idea about the accuracy, I was shooting off hand at 50 t o75 yards and hit the target enough times to enjoy my day  While inspecting my order from AIM (1000rds) I had one seriously bent case and 4 that had small folds in the case neck, those might be considered by some to be splits in the neck. Will order again from AIM. edit to add for the info in the post below, my headstamps all said 04 |

If the year of the ammo is 1999 you are buying ammo that was from the start up phase of the plant and training of employees. The start up phase ammo was sorted with some of it tagged to be distroyed (bad crimps on primers) causing the blown primers etc.
Dents were from the early stages of testing and adjusting of machines and again training of personel. Much of that was to be linked for M249's. So they swiped the floor and sent it over here. Its going to be a coin toss whether you get good ammo or not. Once things were set up (late in 99) it was producing really good stuff. I would not worry about over pressure as that part was covered really well from the very start. The 9mm should be pretty good as it was set up after the 5.56 line and everyone was well trained. Oh, How do I know all this, I was there. Art - Silver State Armory |

I bought 500 rounds from AIM. I liked the price & the ammo is really nice looking so I was really hoping to have a positive experience. Unfortunately, I had blown primers & one primer caused a FTF (the first malf I have ever had in this gun. made me sad). The rifle is a basic 20" A2 built on an Oly lower & a Model1 upper/lower kit (5.56 chamber). I confirmed two blown primers from cases that I saw. I was not collecting brass, so there may have been more. I will shoot the remaining 400 rounds, but I won't buy it again.

well, from what i can tell from just scanning the posts, it looks like the problem barrels seem to be aftermarket types. not to deminish their quality but there might be some tight chambers out there. i had this issue before with custom type barrels.
i took the plunge and bought 500 rounds from AIM. i have 2 white oak barrels and 2 bushy's so we'll see what happens. |

AimSurplus - A223AM Adcom .223 62grn M855 Ball
http://aimsurplus.com/acatalog/copy_of__223.html 2 blown primers in a brand new 16" BM Patrolman. Both ended up in the mags where I could hear them rattling around. No problems in a 16" BM V-Match. *UPDATE* www.AimSurplus.com is replacing the ammo, and paying for all shipping! I have bought several cases of ammo and other things from AIM, and they are a great vendor. Nuts{WoC} |

Update: I shot about 30 rds along with 100 rds of Wolf. The ADCOM ammo worked great in my RRA Elite CAR A4. I feed well, but was not as accurate as the Wolf. Not sure why, just didn't group as well. I will be shooting more soon.

I had a chance to run a few rounds through a guy's chronograph today.
Rifle, RRA 16" Carbine Temp, 25 - 30 deg. F. Distance to chrony, about 10 feet. Velocities - 2930, 2936, 2941, and 2972 fps. For the day, I was able to fire 100 rounds. I had two blown primers. I am probably not going to buy any more. BTW, I have no idea if those numbers are "good" or not. Just reporting the facts. Groucho |

i ran 60 rounds total this morning, temp was about 45 degrees. i had 30 rounds thru a 11.5" bushy and 30 rounds thru a POF 11.5" upper. i had no problems with it but i was not able to inspect each case since the range was pretty littered with brass.

Guess I spoke too soon.
Out of this new batch I went through 150 rounds and had about 5 blown primers, using the same gun I went through the first batch of 1000 which didn' t cause me any problems. Still going to continue to use it, as I knew what I was getting into with this surplus ammo, but I'm not so sure I'd buy it again at this point. The blown primers caused FTF's as the primers got stuck either on the bolt or in the lug recess, preventing the bolt from locking. Ben

I am a new member recently returned to the shooting hobby. I bought an Armalite M15A2 carbine and about 200 rounds of the Adcom M855 ammo at the gun show. No problem at all with the product except for a few dinged up rounds that I didn't want to fire. All in all, it seemed fine to me. I also bought some Wolf ammo and it really seemed crappy. Almost underpowered and completely filthy. I know that isn't very scientific, but in comparison after about 100 rounds I vote for the Adcom hands down. I am going to locate some more and buy it as soon as possible.

Just picked up 3k of it today. I'll give you a report on it tomorrow.
Opened up a box and it looks real nice. Curious to see how it runs in an AC556. If it works as good as S&B greentips, I'll be buying a pantload of it real quick. Well, didn't get to the range today, too tired after driving 1200 miles yesterday. Will post my results with ADCOM ammo as soon as possible. |

I checked the headstamps on the few slightly dented rounds that I kept from my first batch of 1000 that I had 0 blown primers and 0 FTF's with -- all '02. This second batch of 2000 I got all seems to be '99. I went to shoot more today, bringing 10 loaded mags with me. I think I got to the 5th mag before I got so tired of having to clear jams due to the blown primers I left and I'll be unloading the rest of my mags. It just is not fun to shoot when every 10 or 15 rounds you have to clear a jam because the primer is stuck somewhere. At this point I'd look into returning it, but I've had it longer than 30 days  Ben |

Working on my first "k" of 2000 date of manufacture from AIM. I've experienced none of the problems indicated from the '99 produced stuff. So far, no failures at all and an inspection of a sample of the case indicates no dents, split necks, etc. It shoots like any good M855.

Well, OK, but this will muddy your water. Out of 450 rounds fired, I've had four blown primers that I know of. The last one was on 30 December and there was a primer rattling in my magazine. Lot# AML 99M010-002 - Date on head was '99. That said, if the newer ADCOM doesn't exhibit these problems, I'd be inclined to try another 500 or so before taking the plunge. Groucho |

I deprimed and resized an ADCOM case today, and found that the primer pocket is undersized compared to standard Boxer small rifle primers. It may have been an overcrimped case, I will investigate further when time is avaiable.

Bought 500 rounds last week from AIM i think it was. I got all '04 stamps. I took 5 boxes of it to the range today (100 rnds). After reading the feedback here, I planned on inspecting each round before loading it. My first box of 20 I opened had 7 major defected rounds that were unfirable. By unfirable, I mean major neck deformations and things that could cause serious problems. One even had half the bottom of it shaved off and a big gouge down the entire case. Of the 13 others I fired, 1 was a squib. The next box I opened had one major defect, and the rest of the boxes were fine. The ammo seems very accurate and fed and extracted fine. You just gotta inspect them before loading. I'd probably buy the ammo again.

Been following the threads on the this ammo for a while, as I had been hoping that ADCOM would've been the white horse to take the place of the IMI M855 that we'll probably never see again.
Just had a stray thought on the possible cause for the blown primers. .223 sized chambers. Any chance that you folks who are seeing the blown primers have .223 sized chambers vs. 5.56 chambers? Just speculating. -Frank |

I shot around 180 rounds with no problems. It was from 2003 production. There was 6 rounds out of the 180 I didn't load because of neck damage to the shell, one round had a tar like goo around the neck. All the rounds I loaded shot fine but I would suggest inspecting every round. I had no blown primers and no squibs. I doubt I will purchase more when my case runs out. It seems most boxes have rounds with some form of damage.

I originally posted this as a reply in another thread but thought it was worth repeating here
DeJavu! I had the exact same thing happen at the range on Tues. while shooting ADCOM Lot #AML04M010-007. I had to manually extract the casing w/ a cleaning rod while pulling back on the charging handle. It was only the 7th round and I had 10 more mags loaded with the stuff and 700 more rounds still in the ammo can! Needless to say I was a little concerned. After A close inspection of the weapon, I reluctantly continued and fortunatley had no more problems. I think I will also report this to ADCOM and post it in the Ammo thread. Unfortunatley my shooting partner threw out the round while cleaning up, so no photos. However, the ones posted by wile_coyote are quite similar. Choppa I shot a total of 330 ADCOM rounds that day with only the one malfunction. Just glad it didnt KB. |
