Rhino .416 Rem. Not all hunts involve hunting the Big 5. However I have been fortunate enough to take this rhino with the .416 Rem that Neal built for me in 2003. A fairly physical hunt in 110 degree weather, with a healthy dose of humidity. 4 shots with 400gr solids were needed to bring him down. All shots were killing shots (eventually) but at 30 yards with a wounded animal that is faster than you is not the time to admire your handy work.
