Turnbull will, at minimun, rebore/rerifle/rechamber the barrel, and do the minor rework/smoothing to those boltfaces and EJ ports that are on the low side of the tolerance deck.
The .470 Turnbull is made from Starline .50 Alaskan brass, necked to .475" by simply running the cases through the .470 T sizing die.
Bullets must have a .500" nose ection, forward of the forward cannelure, for this cartridge - and are available through Turnbull (for now).
The basic conversion starts at $900
