@@inventor719 your not a inventor your title says powerful IT DENTS PAPER OMG CAN YOU BELIVE IT but seriously dude just think thats like a 200$ pinfire gun your can buy a better airsoft uzi that about the same size you can buy 4 of them
For shotgun style try loading a tiny piece of paper towel then salt in the barrel then another piece of paper towel so it don’t fall out, or instead of salt you can take a magnet up to sand and get the iron out of it and use that
