Where I live, most ranchers and homeowners own and/or carry weapons of this description. For some reason, people from the nearby urban center think it best or humane to dump unwanted pets in our rural area. They fail to realize that the cats multiply unchecked and dogs pack-up wreaking havoc on wildlife populations, livestock, our pets, and us and our kids (ever come across a pack of wild dogs in a rural/wilderness setting? Scary.).
Besides, rippin'-up sawblades hung from a branch at 80 yards with a .223, 7.62X39, and handguns is great fun and practice.
No need for embarassment, though contrition when apprised of your ignorance shows intelligence.
