If after taking a shot at a critter, ejecting the spent case without picking it up because of the excitement of the hunt, you find yourself looking for that piece of brass every time you pass that spot with the hope you just might find it YEARS later. You just might be a (reloading) "gun nut."
And in the traditional sense, after having a shooting session with your nice, replica Hawken rifle, the FIRST thing you do to start the cleaning procedure is to put your DVD copy of "Jeremiah Johnson" in the machine, right in front of the TV, right in the living room, and the wife thinks nothing of it...she usually says, "How'd ya shoot?"
You just might be a very fortunate "gun nut," with a fine, loving and enabling wife, to boot!
