I have a .300 rum with a heavy 30 Inch barrel (krieger). This rifle was built for shooting targets, now i want to start using it for hunting. The barrel has less than 150 rounds through it, so replacing is out of the question. Has anyone had experience, good or bad, of recontouring a barrel after it has been used. Would you recommend doing this? Also, does anyone know smiths that would do this work? I want to contour it to a smaller diameter and flute it. Thanks for any advice you can share.
