I don't see Aoudad as an ideal target for blunt, relatively slow bullets. Plenty of power, but how do you guarantee your shot is going to be 250 yards and in? Are you willing to pass on animals out of that range?
Whenever I debate for myself this kind of stuff, it boils down to whether I'm willing to go home empty-handed because of my self-imposed limitations based on firearm/sight choice.
That said, I think you should follow your interest.
