Re: Gun Cases
My Russian telescope, worth more than any of my rifles, lives in a Pelican case.
My bass guitar lives in an SKB case.
My best rifles cases are ADG Sports, but they aren't going to Africa, they just ride around in my truck. The ADG case is much lighter than Pelican or SKB, but not as strong. It is airline rated, and looks better than Pelican or SKB.
If you can afford a trip to Africa, you can at least afford a Pelican or SKB case. Your porter/guide will be hauling your gear around, so the extra weight shouldn't bother you.
I'm sure there is something lighter and stronger out there at an astronomical price, such as kevlar or something.
