I took a .458 Winchester and a .338 Winchester to Zimbabwe in 2006. I used a good 250 grain bullet at 2650 fps with excellent results. Zebras dropped with one shot. Jackals and duikers did too, without blowing up. Zero pelt damage except for a .338 hole in and out. You will be shooting your light rifle the most, and as a bonus, you can carry more .338 ammo than .375 ammo. The 30:06 is a good round, but .338 bullets are tougher bullets on large trophies and small ones too.
