FatRooster,
Have had both Ridgeline and Mesa in 6.5 CM. Kept the Mesa. Both are 1/2” or better with Hornady Precision Hunter factory ammo. The Ridgeline is slightly lighter weight. At less than $1100 the Mesa is in my opinion the most accurate, complete rifle currently available for the dollar spent. Nothing needed to upgrade or change. I have no experience with the Nosler other than handling. To me they are much heavier and bulky than either CA mentioned.
Good luck,
TG
