The reason I asked about the barrel style is because a few years back, a glut of Savage nutted barrels got dumped into the market. The reamer dimensions were a mess, to put it mildly. Most of them were marked '30 Bench Rest' rather than '30BR' which is the more common reference.
I'd suggest doing a Cerrosafe cast of the chamber to start with, followed by a good inspection with a bore scope. Also, check the barrel twist with the 'cleaning rod method'.
If you like, feel free to send me the chamber cast. Be aware that Cerrosafe with grow about .002-.0025 after about 200 hours. Where are you located?
Good shootin'
