I own 2 CA Ridgelines and both are great shooters. Montana Rifle Co also makes a hell of a nice rifle, hand lapped barrels and fully bedded action.
The Montana Rifle Co will be heavier. I have several, and have brought in quite a few. I really like them but they are not as light. The company is getting their act together and doing better.
I made the mistake of carrying a friend's CA Mesa in 6.5 Creedmoor on a Mouflon hunt last Thanksgiving. I swore I would not own a 6.5 Creedmoor but after that weekend I own a 6.5 Creedmoor chambered Kimber.
The CA is really a nice rifle and a tack driver. I simply prefer the CRF mini-model 70 (MRC) like action in that type hunting rifle. The Kimber is lighter. I think Christensen is a better company and no question has the best trigger on the market - TriggerTech. The Kimber trigger is good too but a goofy shape. I think I will put in a Jard. I much prefer the Model 70 three position safety.
