I recently got a 1907 Savage that has unusual machining on the barrel. There is a ring machined on the outside of the chamber roughly where the slug falls, and the relief for the extractor has been extended about 3/16s of an inch past the usual point. With a cartridge seated, you see that much brass in front of the extractor claw.
Does anyone have any idea what this is? Could it be an armory proofing gun?
