Photos and summary
Alright, here are the "grip and grin" photos. And some parting notes:
Travel: Return was smooth. At Detroit, an airline guy met me with the rifle and walked me to CBP. He was interested in what rifle I had. Hadn't retrieved my other bag, so I left the key and the 4457 with CBP. When I got back, he handed back the form and asked the usual "fruits and seeds" questions. Professional, but actually friendly. On my way. If you go, find a travel agent that does firearms.
Safari Company: I will throw a pitch for Kowas Adventure Safaris. Obviously a sample of one, but I can't imagine how they would have been better. Really took care of me. Great food and drink. Great accommodations (daily laundry!), friendly helpful staff. Note they have another "camp" in the north where they hunt elephant, buffalo, and crocs.
Hunting: Spot and stalk, and the stalk can be arduous. Depend on your PH. Mine (first black PH in Namibia!) was great. You have enough time to shoot, but "take your time in a hurry". Most shots are not challenging for a competent marksman, but they are not necessarily easy. When the game is down they winch it into the safari car (Toyota Land Cruiser pickup) and off you go for a beer. Game in abundance.
Rifles: I was happy with the 338/200 Accubond setup. The other guy hunting there had a 7 Mag. Based on a few discussions, it sounds like the 300 Win Mag is ubiquitous, no surprise. The oryx in particular is legendary for its toughness. Hit 'em hard, I say.
Snakes: Discussion around the campfire with the owner. The puff adders seem to be the concern, but you almost literally have to step on them. But they won't get out of your way. Cobras, surprisingly, were less of a concern. They usually display, and if that doesn't send you on your way, they spit. Mambas, though. The only good thing said was they're rare. But obviously, a big one like we saw is very dangerous. Just stay close to the PH. They have nasty scorpions, too, but I didn't see any.
Overall, absolutely the "trip of a lifetime". I want to go back - everybody does. My $20k budget (all in, including trophy mounting and shipment) is pretty accurate, but you can do it cheaper. Hunt 5 days rather than 7 with these guys, get skull-and-horns mounts, pick lower trophy fee animals. (The kudu is $2,500, the rest much less.) But, go if you are at all able.
