Robert Prudhomme Posted January 25, 2015 Author Share Posted January 25, 2015 I must admit, I am not privy to any scientific methods of determining if a rifle has been fired recently, though this does not mean there aren't any. That being said, just sniffing the chamber or muzzle of a recently fired rifle will let a person, with a good nose, pick up a definite whiff of burnt gunpowder; something not nearly as detectable on a rifle not fired for a few months.
