Sounds like over pressure however it is possible you need to have the bolt face polished and or a chamber reamed to remove a burr. Brass expands quickly and holds heat, therefor even the slights of imperfections from tooling can cause restriction or extraction problems. I would take it to a respected compenent gunsmith, should be able to tell you if it's a simple fix &/or if savage should get involved. A call to savage isn't a bad option. Either way it needs to be addressed before you use or sell it.
As far the tikka if it feels and fits you good go for it. I personally don't like the fit or feel of the tikka T3, so will not buy one on that account alone. However they are good shooters and have a loyal following.
