Anyone know the details of TSA's screening for trace amounts of explosives? Think its called "ETD."

I fly all the time for work, but I'm also an avid target shooter and reloader. Seems like I'd flunk such a test.

So what happens then?

I'm going to jump in with very little knowledge. On a different forum it was discussed and the powders we use, unfired or traces of fired, don't show up since they aren't explosive, they burn. Now black powder is a whole different story. It's got trouble written all over it.

I dunnow about that. Double base powders might give you trouble. If I had Unique ground into the sole of my shoe, the nitroglycerin might cause some excitement.

I've been swabbed several times and always negative.
