I would go this route ^^^^^Lex Webernick, Rifles, Inc. in Texas. He's been building them for over 25 yrs. 4 3/4 lbs.!
Since you mention using a rem 700 I would say go LRI. They are the modern master of 700 action customizing/blueprinting.
Aren’t LRI the ones who charge like $800 for a bedding job? Just wondering what makes them so good?
