Any decent .224" bullet should work if using a 223 for Cape Buffalo. But don't try it with a mere bolt gun......It has to be fired from an AR-15 pattern rifle, AKA an "assault rifle" . Because "everybody knows" that those are "killing machines" and fire bullets at such high velocity that they are incredibly lethal on any living thing they hit. As previously mentioned those ultra high velocity projectiles also tumble on impact and create HUGE wound channels so theoretically a Cape Buffalo wouldn't stand a chance. But don't take my word for it. Ask any big newspaper editor about those deadly bullets.
