The chamber lengths are functionally identical, the chamber change is easy however it's not going to recut any part of the throat like a regular setback would so you're putting a race tires onto a used buggy (the burned barrel, not the 30-06, that caliber is great IMO).
The other things will be:
Extractor, Ejector, and bolt face changes required
Feed ramps in the action changed
Feed lips in the action changed
