mountain hunting

Im trying to decide on a lighter weight mountain hunting rifle that has potential for longer range practice and good accuracy. I was thinking between the bergara m14 wilderness and a christensen arms mesa? Any opinions? 6.5 prc will be the caliber Thanks in advance

I have been trying to decide on a route to go for a new rifle for my brother but can't come to a final conclusion so I am looking for help. I am not sure whether to go with a higher-end factory rifle such as a fierce or a 2020 waypoint but also whether to go for a custom build either by me...
