As a 404 Jeffery owner, I can tell you that 404 brass is available, mostly from private sources, but you might check with Raven Rock Precision - they stock brass for 'safari' calibers. MIGHT even have some .333 Jeff brass. IMO, RWS and Norma make the best 404J brass. Hornady makes runs of 404 brass & ammo from time to time.

Some older Kynoch brass is Berdan primed, so make sure whatever you buy is reloadable.
