I can't help you with the Sako 78, but I do have a Kimber HS. I was lucky and got one the the earlier models. From what I gather, when the Kimber HS were first made, they were made with a Shilen barrel, and none of the detail was skipped during production, however when the company wanted to make more money on them or whatever, they started making their own barrels, using hit and miss tolerences from crown to butplate. If the person trying to sell the rifle has problems with it, I would definetly pass.
