I think we all agree that the 30.06 with 180 grain ammo is a great safari package for PG. However, I recommend you look at other calibers as well. Seems some of the the larger PG are still running strong for 100-200 plus yards after good shots out of a 30.06 with a 180 grain bullet, but that running distance after a well placed shot from one of the 8mm's, such as 325 WSM, 338 Federal, 338-06, 338 WM, and others, seems considerably shorter if any running away even occur....most of these 8mm's have a variety of bullet weights, so smaller PG can be taken too....further experience showed me that heavier bullets from these 8mm's have lesser meat damage than faster lighter bullets. If DG are included in the safari you might consider two rifles, one for PG and one for DG. That will allow you to choose the best PG cartridge you can afford and the best DG cartridge you can afford. However, one of the .375's seems the way to go if you want to buy only one safari rifle. The Ruger M77 and Winchester Mod 70 are good platforms to consider for your rifle.
