Leo or Huckleberry jump in here if I'm off on this.
When one looks at the cost here's something to put some meat on the bone. The flight round trip ticket is around $2k, the hunt could run you $3k, the medical or meds before you go could run a couple hundred (malaria prevention piles, etc) and getting the animals prep and shipping back to the US possibly $1k or more. The Taxidermy service could run you $700 to $1k or more per animal for the mounting. Still I want to go. The memories that friends have shared with me are priceless about bowhunting Africa.
Leo what bow and what setup are you taking this time? I know you learned a lot from your first trip and I imagine you'll be changing a thing or two.
The hunt will be in a Malaria free zone. You need to be up to date on tetanus boosters. Hepatitis immunizations are a good idea but I'll check with the outfitter as I don't think they are required there either. Dip and Pack will run you about $100 per animal. Shipping is by cube size. Obviously mounted heads take up more space than hides and horns.
You also have the option of just bringing back photos. Personally I'm not supposed to get any more as I still have stuff at the taxidermist now (oops). I might have to bring back a couple though...
Same bow as last time Rowdy some minor changes. 70lb bow, 455grn arrows with 125grn heads instead of 100s this time. The biggest lesson I learned was my setup needed those 125grn heads. I also switched to blazers to bump the FOC up a little more. The improvement in FOC makes a big difference in flight and in terminal penetration. I'm slinging these arrows out at 285fps. Plenty of momentum and energy for plains game.
