Re: How hard to take a barrel from R700 and....
So the Badger m2008 action has a 1 1/16- 16(3A) pitch thread.(Barrel Thread: 1 1/16” X 16 3A, 1.37” long) copied from badgers sight. The 3A is a class of threads that holds a very precise tolerence. The remington uses the same thread pitch but I can't state for certain what class threads are on your barrel. To answer your question, your smith should be able to do it with no trouble.
