A 300 grain SST, the Barnes, Nosler, Speer, Parker, ... all would do the trick out to 150 yards, all but the bang flop part. Too many expect a bang/flop. You have to be willing to break them down to achieve that and at 150 yards on a deer that is not always possible. Instead concentrate of the large kill zone, put a big hole through them and their vital organs, and settle for a short walk and a blood trail.

Use loose powder and work your load up from around 80-110 grains of powder. That will get the job done on a White tail. Good luck.
