I have a nice argentiean 1909 Mauser action + a stock for it but no barrel , a friend give me two , nice bores , until I check with a borescope , and measure a bit with a lead bullet , barrel nš1 have nice bore no rust , on the muzzle it's .303 x.311 sharp land and grooves , but a free bore.... it's .316 and I need to push a lead bullet (314299) 40 mm ( 1,5") to find the grooves.. and mesure .306x.313 it have a smooth loooooong frebore , second barrel have at muzzle .304x.313 and at freebore a bit more .305x.314 but grooves and lands are dull and rounded think it's shoot with service corrosive ammo and not cleaned , pits and rust all barrel long , I'm cleaning but still no clean patches , what's your opinion wich one will work better with cast bullets? I'm with Nš1 but not sure about.
Any help appreciated
