[ARCHIVED THREAD] - Problems with IMI 77 gr razor core-update 8-31-16 (Page 1 of 3)

Posted: 6/15/2016 6:34:21 PM EDT

Just had massive blown primers on a batch of IMI razor core 77gr 5.56- 8 boxes total all Lot 00229/F. Experienced 6-8 rds per box of 20 with same issues. 4 different rifles- 3 X LMT and 1 X Colt. No issues with other ammo shot today - Black hills and Fed M855

All rifles have less then 2K through each, bolts/ headspace all good to go

Ive emailed IMI IN Israel and waiting to hear what they have to say. IMI ammo store online is just a reseller Ammo in question could be from wideners or SGA

will update as I hear back from them

I also have this lot number, 500 rounds. I have shot 20 rounds without an issue, for what it's worth. I'm very interested to see how IMI responds,

I have a couple boxes of this lot and no issues with what I've shot.

No response yet. I can't find a US based point of contact. A little discerning, that I can't track anyone down

Posted: 6/17/2016 11:56:20 AM EDT

Just confirming, one of y'all has emailed Sam at SGAMMO?

Yes

my 77gr razor was all older stock in the brown box from wideners in 2013/14 whatever. i've burned through 1000 rounds of it and had no issues.

i do have 1000 of the new green box 55gr from SG though. guess i better demo a few hundred this weekend...

i see AIM has brown box 77gr lot 239. funny how the box color changes so much too. anyone have this stuff?

Posted: 6/17/2016 5:00:29 PM EDT

[#12]

Yep. I had good results with it this past weekend. I'll post lot numbers later tonight.

Posted: 6/17/2016 5:21:08 PM EDT

[#13]

Yikes I'll have to go through the vault after work.

Posted: 6/17/2016 5:28:56 PM EDT

[#14]

I've never had any issues with the brown box stuff- have shot A LOT of that over the last year and half

Posted: 6/17/2016 11:37:19 PM EDT

[#15]

Bought a single box at Cabela's a while ago to try this stuff... guess what lot number it is.

Posted: 6/18/2016 10:57:04 AM EDT

Yes they were first go to. They are not IMI just a reseller . The lady who answered had no info for me , other then to tell me they were not IMI and was very adamant about saying they didn't sell the 77gr stuff

When you say blown primer, do you mean the primer itself blew out of the pocket, or the firing pin punched a hole in the primer?

I had two primers blow out of IMI 175gr, and later had a problem with scraps of brass (primer parts?) filling the firing pin channels on two bolts. I also noticed, what looks like a very nice blast ring, around primer width, on the front of my SR25 bolt face, and it will not scrub off.

I have a thread on page one of this forum with my experiences.

I did not have the same problems with my SPRish rifle shooting about 80 rounds of IMI 77gr.

Posted: 6/18/2016 1:13:27 PM EDT

[#19]

Primers completely blown out of their pockets- falling out into gun. Cases are ejecting

Posted: 6/18/2016 1:20:58 PM EDT

[#20]

When's the last time you scrubbed the chambers?

Temperature?

Posted: 6/18/2016 6:16:27 PM EDT

[#21]

Chambers were very clean. Temp was mid 60's. Very slow fire in all rifles-irons and optics being zeroed- no more then 4-6 rds loaded in mags during the issues

It's not a rifle/temp issue No issues whatsoever with Black hills and Federal during same session.

Did you take pictures of the casings

Posted: 6/18/2016 10:40:22 PM EDT

[#23]

I have 7 boxes of that lot that I haven't shot. I guess, I will be following this thread for outcome.

the brown box lot # 214 that I have is good to go. I've shot lots of it without issue.

Posted: 6/19/2016 12:43:49 AM EDT

[#24]

I have several cases and recovered primers. Don't know how to post pictures

I'm running low and shot 5 yesterday to confirm zero on my A4 clone. Temp was 95 degrees, no issues at all. As I stated earlier what I have is from the same lot as the OP. Here is a pic of the case heads.

Posted: 6/22/2016 2:49:19 PM EDT

[#27]

Any update to this?

Posted: 6/23/2016 8:42:52 AM EDT

[#28]

I've gone through at least 5 boxes of this same lot, with no issues.

Temps from 40-90f in a .223wylde chamber. Unless you guys have .223rem or very dirty chambers I don't know why you'd be having issues.

No reply yet from IMI. Ammo was purchased at cabelas They are passing it off on IMI and not doing anything as ammo is non refundable.
As I stated before- guns are clean, way in spec, good quality mfg ( colt and lmt) mild temps, and slow fire. Problem was just with this lot. Other ammo fired as same time had no issues. Previous lots of this ammo was always good to go in these rifles. I'm gonna reach out to a couple other vendors that carry this ammo and see if they have a POC for IMI

Upon further inspection, brass looks soft- cases with blown primers have clear ejector indentions and extractor indentions- very prominent I'm going to try posting pics later today

Posted: 6/24/2016 11:16:51 PM EDT

[#34]

Shot 100 rds from this lot today is with no issues. Interested in what the manufacturer says.

It's not from soft brass. Blown primers coupled with ejector indentations is a clear sign of over pressure.

You're welcome. It was late, I was tired and didn't want to explain last night.

On Photobucket, you are presented with multiple options to "Share this photo".

1) Click the "Direct" link, and it should automatically be copied to your clipboard.
2) Here on Arfcom, when composing a message, click the Image icon (looks like a mountain), paste what you just copied into the pop-up window and press ok.

The result will look like this without the spaces in the img tags:
[ img ]http://i1378.photobucket.com/albums/ah105/photobucketuserid/IMI%20issues/image_zpsv6uidxep.jpeg[ /img ]

For imgur, you need to be sure to use the direct link to the image and not a link to the imgur page/album/gallery.
1) Right-click, view image
2) Copy the URL from your browser's address bar. Example: http://i.imgur.com/SBgwJ63.jpg
3) Here on Arfcom... just like I said above.

EDIT: Proof that the imgur link worked.

These directions are for Firefox, but IE and Chrome will operate similarly.

IMI USA finally got back to me. I forwarded them pictures and info so they can get with their QC in Israel. Will post when I hear back

Thanks for update

Posted: 6/28/2016 10:52:28 PM EDT

I do not recall seeing the mentioned email above but just saw this post. I never had a single complaint about this ammo when I had it. We have a shipment coming in about 20 days of this same stuff, not sure what lot # it will be

Thanks

metro6, is your lot from the craft brown boxes or the new green ones?

Posted: 6/29/2016 1:20:05 PM EDT

[#47]

New green ones is this lot

Zero issues with the lot 00239/F

Had problems on primers backing out on some IMI 308 last year. Wasn't the only one, good thread on it over on the M14Forums. Widener's gave me my money back for them.
Haven't had any problems with the 1500 rounds of IMI 77 grain razor core I've shoot, but none of mine are OPs lot number.
