It's one thing to say you're gonna hit something at 700 yards, it another to hit it. What does it cost to shoot a .409? how much to reload? Fuckin bunch I bet. That means little or no practice. So you're gonna buy this cannon shoot 3 shots to sight in at 100 yds, climb a fuckin tree and try to hit a deer at 700+? BUUWAAAAA!!!! Just get a fuckin .308 and load your own rounds. figure out trajectory and practice.
