I have a Brazilian 98 Mauser with a 7.62 (308) barrel. The barrel has been damaged by using a treading die to remove a stuck case. The chamber now has a series of thread marks up one side making it worthless as-is.
Question 1: Can a typical military Mauser barrel be set-back like a 1903 Springfield barrel, to clean up a damaged chamber? There is a 'short' shoulder with questionable depth (?) to set back one turn of the treads.
Question 2: If the damaged barrel can't be salvaged, is there a source where a military contour barrel with military sights can be purchased to keep this rifle in 308 caliber?
I sure would appreciate hearing from someone who has encountered this problem and knows of a cure! TIA
