If it was me I'd farm out the barrel/chamber work. But I don't mean to divert your enthusiasm.
Installing a barrel and getting the chamber/headspace/extractor slot right is a tall order for a first timer(I've never attempted it). Not that it can't be accomplished, but a tall order nonetheless. There's a lot that can be done to a rifle, less demanding tasks, once it is barreled,
AGI has good videos to learn from, among others. Poke around and see how they do it.

Those Kimbers were nice rifles, I missed the boat when they sold them some years back. Swedes are quality rifles and you can't beat the cartridge.
Good luck with this, you already have a good start.
