I'd never want a .700 NE, but a 2,4,or 8 bore, might be an idea! I don't think so though, I saw one once not sure which one it was, but it shot a bullet of 1" diameter. crazy. Sounds like a .470 or .500 has much more of a place in modern hunting than .577 or .600 I read that even back then most of those PH used a 375-.458 then only in thick brush after a woulded beast did they grab a .577
