Methyl Chloroform???
Picked up a pile of ammo today from an auction on sunday. One of the cases is 1000 rds of 5.56 green tip SS109 ammo. On the outside of the case is printed a warning that it may contain "Methyl Chloroform".
I don't recall having seen this warning on ammo boxes before. Is this chemical used in solvent to clean the brass? Might it still be present in the ammo components?

Likely evaporated a long time ago. There is no such thing as zero, only limited detectors.

I don't remember seeing that warning.. I wonder if it could have been used to treat/prevent any mold/mildew.. I know years ago I used trichlor sometimes to get rid of the musty, damp smell from antique furniture.. 0 -

I'm not sure why that compound is in there; my guess is its probably present in the PACKAGING of the rounds not the actual ammo. Are they in vinyl bags or such?
In any case, assuming the ammo is sealed containers more likely than not there is still trace amounts of it in there, and its probably leaching out slowly over time.
Wouldn't worry about it though. The stuff dissipates quickly on exposure to air, and its not really harmful unless you concentrate it an inhale in large quantities. It could be irritating to skin, but since you're probably not going to bathe in the ammo containers, again, no worries.0 -
Probably was used to remove any oil residue from the cartridges after manufacture. As previously stated, there is probably the faintest hint of residue so the .gov in their wisdom requires the warning. 0
