Eight is enough. No, not the television show, I'm answering your question. And wondering how many people under forty have no idea what we're all going on about... Anyway, my own HD shotgun holds five. There's another box of 00 buck handy that I'll drop into my pajama pocket if need arises. Which I hope never does. Because if it's not over before I've expended five rounds, we're in deep doo-doo.
