I know that there are less-lethal "beanbag"-rounds for shotguns.
But do less lethal rounds also exist for rifles or pistols, or do they only exist for shotguns?
There also use to be something called Rock Salt. Have to see if that's still available. Apparently it would break the skin and then burn like fire but not kill you but you'd wish you were dead. Not really. Read this. You've got to be almost point blank range for it to do anything according to this article.
It's for a book project, and before I make them up I wondered if it exists.
In the book they try to slow down (but not kill) a guy from a few hundred yards away, clearly out of range for any shotgun.
