Like Dean2, I have been many times also. With cull hunts and trophies probably 150+ animals. I have always used heavy for caliber triple shocks, accubonds or partitions. I would strongly suggest getting Dr. Kevin Robertson's "The Perfect Shot II". You will be surprised the vital organs are not where you think they are relative to north American game. Much further forward. FWIW the PH's all love triple shocks and A-frames. Enjoy your hunt, you will have the time of your life!
