So we are back in unlikely scenario land. As long as we are here, what are the conditions where you would “need to take” a 700+ yard steep quartering away or a butt-hole shot? I’m seriously wondering if that should be a marketing thing. “When you really need it, nothing destroys a butt-hole from a half mile away like a 28 Ass-Womper.” I wonder why Nosler never thought of that.If we actually want to be realistic to the question and hunting conditions I don’t think the price has anything to do with it I think a 22 cal or 24 cal would be a pretty great choice for Marco Polo and Mountain Nyala but I don’t think it would be ideal to the conditions they live in. Marco Polo is a very rugged hunt and it’s a good possibility that you could be taking a 700+yd shot on one across a canyon in very high gusting winds, I think something along the line of a 28 cal magnum with a super high bc bullet would be an ideal choice for the hunt. As for the Mountain Nyala they are very very skittish to begin with and they live in a very thick environment the hardest part would be getting eyes on one and good shot opportunity’s are few and far between, the chance of taking a less than ideal shot on one would be pretty high. As for the caliber I think a something along the lines of a 28 or 30 cal with a controlled expansion or copper bullet would be pretty good or even something like a 375H&H if you needed take an extremely steep quartering or even a “Texas heart shot ”.
