Let's start at the beginning...

Back when I had my Cetme, I'd find one kind of ammo that worked and stick with it for fear of blowing my face to pieces... so it'd be very rare that I'd try new ammo... I tried something surplus I found at the shop for cheap, but it didn't extract very well, so the rest of it went into my closet. I sold my Cetme and put the money towards a DPMS lr-308, so I'm kinda' curious...

The Question:
How do I tell if this ammunition is corrosive?

I don't have the boxes they came in anymore - and for the sake of experiment, I won't post the headstamp. Is there any other way to tell if this ammo is corrosive?

I have made the following test for corrosive primers.
take a sheet of steel and polish several spots with a sander pad.
Take your test cartridge; pull the bullet and dump the powder.
then fire the primed case so that the residue hits the polished
spot on the plate.
You can do a control using known non-corrosive ammo. If the test ammo
is corrosive; after several days it will be rusting where the primer residue
hit the steel plate.
 
Hmm... well I don't think that the people in the apartment next to me would appreciate a test like that! :)

How do you do that? As a kid we pulled apart rim fire and shotgun, but is there one way that's better than another for center fire? I haven't gotten into reloading yet, so please forgive my ignorance.

7.62x51 Nato stamped is all non-corrosive it never was corrosive. The delayed blowbacks Cetme, H&K foul the chamber and nead to be cleaned after shooting.
 
Gunner03, most of the reloading mfgrs make a 'bullet puller' or 'kinitic puller'. It looks like a plastic hammer. The loaded round is put in one side of the 'hammer head', the other 'hammer head' is rapped smartly on a hard surface. The bullet is disloged and comes out along with the powder. The case/primer remains intact.

Most smart reloaders will pull a sample of their reloads to verify their work.
 
If there is doubt whether corrosive or not, treat it like it IS. Not a big deal. Just change your cleaning regimen a bit to account for the possibility of salt residue.

Does not hurt the firearm to 'corrosively clean' it...and better safe than sorry.
