I agree with grit, it is most likely all the way through. Are you sure it isnt just a scratch.? The problem is it may have been there from the factory or happend last time you shot it. I doubt it is a cartridge problem as the bolt head takes all the stress and none or little transfered to the bolt body due to the floating bolt head. If you call Savage and they want to sell you a new bolt, decline. You can get them cheaper at Midway or Brownells. I doubt it would cause any danger due to the fact little or no stress is put on th bolt body but I would change it anyway just to be safe.
