First, crop and resize the pictures. Yours are huge in monitor display terms.

The failure in the picture is identical to the 5 failures I have had with reconditioned LC brass. The load was 43 grains I4064 with 155 grain Nosler Custom Completion bullets. See,308 case fail thread.

This has shaken my trust in this ammo.

Wow... I just sold a box of 100 rounds of this ammo at an auction and now I feel like a rat.
I think I should track down the buyer a get it back.

Has there been any recall of this ammo?
Any respectable manufacturer would recall this crap.

I still have 2 hundred more rounds of this crap.
What to do?

I visited the Atomic web site. Wow... It is not reassuring.

Sad,
Maj

Like Major, I am sad about this ammo. I have only 1 can but am glad I never shot any of it. If anyone has any ideas about what to do besides breaking it down for components let me know.

Or, if anyone is in the Richmond,VA area and wants to stop by and make a small donation for it I am open to offers.

That is a real interesting case split. Never seen one like that before. That lot of brass should be condemned. The pulled and weighed loads do not seem to be excessive.

Exactly the same issue as I experienced this year during the team match at Perry. The photos are a carbon copy of the case split and magazine blowout. Curious if it's the same headstamp. I'll check when I Get home and post so we can compare.

Default Head stamp info

The case that I had separate (the one in the picture) is lake city and is marked with the L C initial and 07 date with the NATO symbol.

Sorting through the unfired rounds I see lake city from 90's through 2010 with a few other various case brands.

I have been in contact with manufacturer,who while out of town on business has replied to my email and photos and asked me to completely discontinue using the ammo and we will be discussing this when he returns from trip this coming week.

So I will update and if anyone has had issues share them.

I just fired reloads of Atomic LC 07 (3rd firing - 1st probably through a mil machine gun, 2nd as an Atomic reload, 3rd as one of my 42 gr IMR 4895 under 175 SMK jobs).

I fired through a Remington 700 bolt.

Im not cheerleading Atomic. Obviously there are issues.

Im used to seeing separations slightly higher on the case, the stress type we check for with a paperclip related to too many firings.

Are these issues all M1A related? Sharp extractor? Violent load cycle.

Most of my Atomic was initially fired through an LMT (AR10) .308. Its a violent load cycle especially as the gun is overgassed but the extractor is not the beast a Garand/M1A claw is.

There is nothing an M1A will "do" to brass to cause failures. The brass probably had defects before loading, either manufacturing-related or related to previous use.

The brass cracked through the web. The web is solid, except for the flash hole. My guess, and it is only a guess, is the brass was annealed improperly. Except for an extreme overload, that is the only thing I can think of that can cause a crack through the web. This defect was responsible for many, if not most, of the ammunition failures that blew up LN '03s.
