OK, here comes the real advice!...Get a Remington 700 action. Have the bolt sleeved and the action blue printed. Throw a Timney or Jewel trigger in it. As far as barrels go I would go with a Hart or Krieger. Put it in either a McMillan or HS Precision stock. Go with a Ken Farrel Base and rings, or Badger Ordinance. I live a half hour from a guy that makes THE best guns out there. He is building them for the US team. He specializes in target rifles and makes a lot of 1000 yard match rifles. If you can get a 700 action before the introduction of the "J" lock. If not it can be modified. Scopes??? Hmmm, if you want the high end shit go with a Nightforce or Zeiss.
