I've been wondering, how effective is a shotgun? What I mean by that is, it seems to me that a shotgun wouldn't have a lot of stopping power because it fires beads, not bullets. I think beads wouldn't go in very far compared to bullets. I'm referring to a double barrel 12 gauge shotgun firing buckshots. Do you think that shotgun would do a lot of damage? I've never fired a shotgun before, so I obviously don't have any experience. Or are the beads like lots of bullets being fired out at once? Thanks!
