I used a Kimber Montana in 7-08 and 120 Barnes TTSX to take warthog, impala and blesbuck, all one shot kills. I used a Sako A7S in 270 Winchester and Sako factory 156 Hammerheads to take my Kudu and Gemsbok, both dropped at the shot but both needed finishers. Most of the group that I was hunting with were using 30-06's and did well. My partner used a Winchester Featherweight in 270 and 150 grain bullets, I don't remember the flavor. If I go again, I will take a pair of Nosler Outfitters in 35 Whelen and 30-06 both shooting 180 grain bullets. Good luck.
