Carlsbad can open the boltface up.Since you have a Farley with a PPC bolt face you might as well forget sending it back to Farley to open up the boltface. If you want to go that route you would have to find a gunsmith that has a jig sent up for a Farley bolt if you want to open it up to .473. If it were me I'd just get another barrel chambered in 6PPC and run with it.
