Walking, hunting animals of opportunity, but carrying a rifle big enough to to keep the really nasty ones from dancing on your dead carcass, and carrying everything, every day, leaves me with only one choice. A good 9.3x62 loaded with with softs and solids chambered in a light weight, modern & reliable bolt action. CZ 550 at the low end, original Mauser 98, and several similar custom variations at the higher end. Sighted with a compact fixed power scope in good QD mounts and irons, or better yet a pop up receiver sight. And a sling. No detachable magazines, set triggers, muzzle brakes, or other fluff. Stock would be stable laminated wood, or synthetic. Steel could be coated with a good rust proof finish or stainless. I would not wonder if I could do better.
