Well, I don't know about Africa but it shoots pretty well in the summer even when it's in the 90's. And at the other end of the spectrum, last year the morning of opening day it was 6 degrees BELOW zero and I had no propblems at all with gun or scope. So there's about a 100 degree spread for ya!

Edit: That was opening day in Minnesota when it was -6. A tough night in the tent!
