I will never be in position to spend $6,000 on a rifle (well maybe if I win the lotto...). But, I would think that even if you aren't a world class shooter it would at least buy some peace of mind that any issues are virtually certain to be with you, not your equipment.
Plus, doesn't McMillan do CRF actions? Custom CRF actions are hard to find. Montana Rifles, Dakota Arms, and McMillan are the only custom CRF actions/rifles I know of. Unless you find an M98 action to piece into a rifle (PITA shipping, etc) or you want to chop up a Winnie or Kimber....
CRF rifles ain't as plug-and-play as an M700 or Savage. Some people just gotta have the claw, I guess.
