Do any of you guys who shoot the "Big Bores" NOT reload?

I've been reading alot of good stuff on the 404 Jeffery -- I like the practicality and the nostalgia of a round like this, but I can't find factory ammo for the Jeffery. Ammo for the 416 Rigby it is like $120 a box in Cabelas.

What would it cost to load a box (of 20) 404 Jeffery's? Where would you get brass? I don't reload, but am curious.
