The 17 Mach IV will chamber in the 17 Fireball but the 17 Fireball will not chamber in the 17 Mach IV. The fireball is wider at the shoulder by . 006". So the Mach IV dies will load both cartridges but will work the Fireball more when FL resizing and the Fireball will not size the Mach IV at the shoulder.

You could, but why? In real life they are just the same thing. A Fireball at the end of the day is just a sloppy Mach IV chamber. I’d keep things as is, for nostalgia and the better-fit brass.
The friend of mine who owns the rifle does not reload. He is in PA and I am now in NC (WV then NJ before that). To make Mach IV brass from .221 FB requires at least three dies. ( I might be wrong about that)
I used to do all of his reloading when I lived in NJ (74 miles) but not now living in NC (800 miles).
It would be simpler for him to just buy .17 Rem Fireball.
I will see him in July. I could take the rifle home with me buy the dies needed and make 100 cases work up a load and ship him back the rifle and loaded cases.
He is the type where money in not an obstical.
