My friend has nearly 22 preference points for Big Horn Sheep. He is currently building a new custom rifle in 7mm magnum, and is a very experienced hunter. The twist rate of his new rifle is 8.5".

I am on a mission to determine what bullet choices he should consider, should he get drawn in the next few years.

Items to consider.
He is comfortable shooting up to 450yds-500yds
Wind
Elevation
Drop animal in his tracks
Cape damage
Proven

Your help is greatly appreciated.
