I just use 000 or 0000 steel wool to clean up the green corrosion and set aside to shoot first.

was going over this thread and regarding the black stuff around the case mouth....I only have DAG and they do not have sealant. I don't have any MEN. Does any of the MEN have sealant?

He doesn't say. I'm sure it was Dag or Men though.

Gents, I just looked again to be sure and it's DAG 93. Looked through about 50 rounds that I had cleaned and have pink showing through on about 10 of them. ALL had been cleaned with scotch bright pads and 0000 steel wool and I had not noticed the pink then. Course after about 500 rounds, one tends to get cross eyed and maybe I didn't check as good as I should have. Found a battle pack of MEN that I'm going to open and check here shortly. Will post if there are any issues with that.

BTW. The black tar like "Stuff" was on the DAG ammo.

Please excuse me if I missed this....
It looks like ALL the pink-corroded cases were on penetrated cartridges. That seems to be the consensus from this wonderful discussion. Possibly an interaction of the corrosion with the powder?
I think I will shortcut my inspection system from this point on and discard/disassemble all surplus rounds displaying even a hint of pink discoloration.

hello

just to contribute to this post, here is some brass I've shooted.. Don't know if the hole was here before firing (I think not) but no damage during fire.

However, the corrosion is very hard....

I stop immediatly firing this lot (DAG 93) and ask for return.


Thanks from m14nm

Maxfr....if you still have that brass,
can you post the headstamp...it should read DAG93 000xxx...the last 6 numbers being the batch number?

Thanks for the pictures Maxfr.

My guess would be that the hole was there, just sealed off with corrosion, making the hole not so conspicuous.

Well after reading this I had to rip open my DAG battle packs ( 1993 ) and look at it. Stuff was clean as a whistle, but I was surprised to see that the bullets had a steel ( or magnetic at least ) jacket. Anyway, I feel better after looking at it as I had a sinking feeling as I read this information.

actually the bullets are lead core steel cased with a copper-nickel "coating" which gives it the silver color...I think the nickel was formulated to withstand salt water exposure.... there is some warnings about bore cleaning with ammonia based solvents after using cupro-nickel ammunition that may or not be relevant today but was significant during WWII. Something about the ammonia and the nickel content becoming hydroscopic and causing rust in the barrel......

Went to a local gun show this afternoon and picked up 5 boxes (sealed) of DAG 93A0303 ammo. When I got home I opened all 5 boxes and here is what I found:
23 rounds have minor to severe pinkish corrosion, 19 has green corrosion and 58 are good to go. 23% toss rate is NO bargain, no matter what the price paid. I'm done with this German surplus. 2 items that jumped out at me outside of the percentage of bad rounds; I found pink corroded rounds in the center row which tells me that the corrosion isn't caused by the rounds touching the paper box and 2 - which scares me - I found many rounds with tiny 1 or 2 pinhead sized pink corrosion marks lower down the round, say 1/2 above the rim. If I hadn't closely looked at all rounds I would have said they were good to go. Now I have to go back through all my other rounds to check for this.

Thanks to M14nm for the pictures. I'd like to ask if anyone else has shot any of this ammo or has heard of any problems doing so.

I can't tell you much about them other than I bought 5 cases of it about 1-1/2 years ago when the prices were down a bit. All mine are DAG93000337 and so far after initially sampling a couple of boxes out of each case and then going through two complete cases. I came accross 1 round with green corrosion of 2mm in length and it wasn't against the paper...statistically means nothing.

Whether the 305 or 309(last 3 digits) is a earlier or later production than the 337's I don't know. I would guess that it would be later. The letter A in your sequence may designate which factory or something like that. I suppose doing a search in google may turn something up.......wouldn't that be great???

If there is anybody else out there with different headstamps on either DAG or MEN...to post it here......who know's ...might be able to drive the price down on what is still out there....

In an ealier post, there was a German military reservist that had some knowledge of the the surplus inspection process.
