I suggest you right click on the chart and save it to your computer with a descriptive name.

Same for this chart. Sadly it doesn't include or say anything about NAMMO or the AYR ammo. Seeing it included in this chart or the information at the link in the post above would sure be definitive for all concerned. Instead, as far as I'm concerned, I don't know what to think or believe.

I say this because I was always told up until the late 50-s or into the early 60's, depending on the manufacturer, if European made and Berdan primed, treat it as corrosive. Thing is, because I have NEVER shot corrosive ammo nor did I plan on it, I never worried about it nor did I concern myself one way or the other with what I was told as stated above. As I've said in most every other post on threads regarding this, ASK ME, I HAVEN'T A CLUE!

Just poking around this thread and saw the remarks about the loose stuff having WWII corrosive rounds mixed in with the HXP. My understanding was that this ammo, in spite of the "joke" about it being "floor sweepings", came off of linked ammo belts. CMP has a crew that was sitin', delinkn' and countin' and filling the ammo cans. I will assume that the counting was just base on 200+ round belts. And since mine have all been OVER the 200 count they didn't count each case as they dropped them in those cans.
I can't imagine those folks looking at every case head stamp to be sure we didn't get a "bad" one.

BUT, all that said I do think CMP should change the description a bit. Maybe caution us that there "might" be other head stamps and "some" corrosive rounds mixed in.
What I won't complain about is the 200+ LC rounds ( non C ), the 100+ Winchester mix in the last few cans. Of the 1000 or so rounds I have received I have had only a very few corrosive, maybe 10+.
I'd still change the description a little just to CYA. :D

If that's the case, I wonder what happened to the links and/or belts.

SL 52 Headstamp
 
I have four enbloc clips SL52 headstamped 30.06 in brw1 clips. After reading the chart, without having the lot number, I am unsure whether it is corrosive or not. What do you think? As always, any help is appreciated.

J.R.2009 09-29-2012 09:05 AM

I'll be corrected if I am wrong but I don't think any of the SL 52 stuff was corrosive. I THINK I heard/read that the cut off for U.S. corrosive ammo in 06 was 52.

If the ammo you're checking is not boxed in original containers, and you can't discern the lot numbers, add one year to the headstamp to be safe.
