I would absolutely carry one. Open carry but I don't know about concealing the thing, maybe a winter time CCW. I don't doubt the killing power of a round ball one bit. I've taken down a many a deer with buck shot which is nothing more than a .33 cal lead round ball. And I can't tell you how many times just ONE pellet in the bread basket did the job!! But I would probably practice with conicals and have them loaded up when carrying one.
