I have even travelled with a powder thrower.. had THAT in my carry on (it's an expensive item and not terribly rugged) and presumably because it was an unusual looking thing they took it out of the bag and wiped the swab around
the interior of the powder reservoir....
NO result...
So.. from that experience.. I wouldn't be real concerned about flying after being at the range!

Unless you use a flintlock rifle and pour gunpowder down the barrel before you drop the ball inside, and get most of it on you than inside the barrel, you don't have to worry about going to the range.
While John Rambo has those explosive arrowheads that pack more punch than a B-52 strike, that's about what it would take for an ETD to alarm off of firearm residue.
Interestingly enough, certain fireworks will alarm the machine. Kind of makes you wonder what it is we're playing with every New Year's Eve or Fourth of July, eh?
