My understanding is that if a target ix 6 feet away or more, they wouldn’t get residue.
‘My understanding is that if a target ix 6 feet away or more, they wouldn’t get residue.’
Here is some info that may or may not be helpful. Either way, it’s interesting:
“Tests show that people standing within 3 feet to the side of a shooter may have GSR on their hands, whereas those standing 10 or more feet in the same direction typically will not.6 This can vary with the type of gun and ammunition, number of shots fired, and the environment of the shooting. Gunshot primer residue also can travel downrange with each firing of a weapon.7 Long guns, like rifles and shotguns, tend to leave less GSR on shooters than handguns.”
