ChiefShotguns,
Have you verified that RCBS doesn't have .221Fireball Ackley Improved on their list of special dies( or CH4D for that matter).Then you should be able to just use a .38 spec.shellholder with them.Dies from their special list should still be cheaper than custom dies.Sounds like a neat rifle,do I know the gunsmith?
