I don't know Zee personally, but he may be a man like myself that likes to push limitations. Thank god as handgun hunters that we decided to push limitations. If we hadn't done that we'd never have the 454 Casull or any other the other high performance handgun hunting rounds. It's all about preference, and if Zee likes single shots....why not shoot a 500 S&W....or better yet, a 50 B&M Alaskan???
