I have a bit of a mistry. I picked up a Savage model 10 308 (that is what the barrel says). When I put the serial number into Savage web site it comes up as a model 12 243 date Nov 21, 2005. The barrel is a bull 22" (measured from the front of the barrel nut). The Customer services rep. did not have a answer. The barrel nut looks perfect with no marks like the barrel had been replaced. I love the gun just trying to find our a little history. Any thoughts. This is my first post so I hope this is in the right area.
