I completely disagree.
One’s bullet is quite literally one of the biggest factors in determining success. It’s much more important than one’s flight choice, taxidermist, shoes, scope, etc. For a traveling hunter who’s spending thousands of dollars (likely ten thousand plus), trying to save $20 by skimping on a box of ammo seems penny wise but pound foolish.
Maybe it’s me but I have the same logic hunting here in the states. Most hunters step up to a premium bullet for Elk, Moose, Caribou, Sheep, etc. They’re no tougher than PG in Africa. Once you look at lease costs, travel costs, time invested, etc why skimp on your ammo to try and save $20. I shoot and best most ammo I can. That’s fusions & partitions out of my AR on pigs, TSS on Turkey’s, and quality bullets like Terminal Ascent, Sciroccos, Bergers, TTSX, TSX, A-Frames, and Bear Claws on Deer or anything else.
