I know they wouldn't be good for much else other then shooting cans, paper, rats/mice in your house and if your close enough, the odd squirrel or so. But I seen these in the local Walmart, told my girl and the look on her face said "Oh my god!! Gotta get those!!" and more then likely would of grabbed a box if A) the dang person for that department was there and B) I wasn't worried about how it'd effect my rifling. So two quick questions, first is what's your guys thoughts on these shot shells? The second is how can you tell if a rifled barrel will shoot these with out being destroyed to the point it sends a tumbling ball of lead down range after a could of these shells?
