I got to go with Mordis on this. I don't see the need for chrome. I can't think of a top notch barrel maker that offers chrome lined match barrels. The idea of lapping the reciever and bolt face ruins the reciever for you next barrel. If you are not shooting competition you most likely never shoot out a barrel.
Big Mag's and high performance loads eat up Brls. My 300 Win Mag has noticable wear at 1 at 1000 rounds. A 06 and 308 in a Garand for casual shooting shoud be good for 10K rounds
