No, this is not a chemistry quiz. Well, sort of. When I was kid back in the day there was a chemical solution used to determine if a rifle had actually been fired or not. Swab the bore, bolt-head, gas cylinder, anywhere on/in the peice that would have been exposed to ignition or propellant gasses in firing and the solution reacts, changing color I think. Anybody know of something like this ? What the solution might be made up of ? Thank you for any help.
