Granted, one should know their limitations, but I've dropped deer with a 223. I only go for head shots with that caliber, but that's a completely different can of worms.
I doubt I'd ever take a shot over 150 yards though.
Of course those who claim they can shoot 1 inch groups free standing at 200 yards in a hurricane are exempt from accepted minimums.
That's easy, I can do that shooting from the hip.
