I have done 3 Sararis to Zimbabwe, and hunted several different areas.

A 21 day hunt in 2004 and a 30 day hunt in Feb 2006, and a 35 day hunt in Oct/Nov 2006.

If I had the money I would be there now.

The "secret" is a good company, and a good PH.

I would prefer the 375 to the 338, mainly because I would want to have good solids for my "light" rifle.

On all 3 of my Safaris I used a big bore double and a 9,3x74R double as my "light" rifle.

I did shoot a few small animals with my wifes Blaser R 93 in 308, just because "it was there".

JPK has given you good advice.
