You're joking right? 600 animals at a time hunting? To kill that many animals in a day you would have to have them in a pen even then that's a ridiculous amount. The logistics of actually doing that, carrying ammunition, shooting, moving, carrying other gear, etc. I've been out with teams of guys to wipe out hogs and we would kill well over a hundred in a day with 16-18 shooters going after big groups. They were destroying farmers crops and would pile in the field in groups of 30-80 and we would unload with a fire team doing a mad minute. Either you're joking or he's telling a big fish story.
