You know, after handling a few rounds, you got that black powder residue on your hands.  Is it unwanted residue from the mfg process or is it some kind of lubricant (graphite?  moly?) that was added for a reason?

I'm not referring to the asphaltum on the neck casing, I'm talking about the thin film of powder(ish) stuff thata you don't really see until it ends up on your finger after loading a couple of mags.

As I mentioned, it is like powder so--->Dust type.  I'm not complaining, just wondering if it was a dry lube that served a purpose so I'll know not to wipe it off.

Are you sure it simply isn't brass tarnish?

All automated loading machines spill small amounts of powder, and the graphite gets on the brass and everywhere else, and the cleaning media that the brass is tumbled in before being packaged (assuming this is commercial ammo) doesn't remove it entirely.

Beyond that, if we're talking about non-tumbled-clean military ammo, there is also black soot left over from the anealing process at the neck/shoulder area.  That also gets on your hands as you handle the ammo.

Thanks, I knew you'd know

I always figured it was lead residue.
