"...Liman's(sic) catalogue has nothing..." Look in a loading manual, not the catalogue. My old Lyman 45th Edition manual has data for it with cast bullets only. So does the Lyman Pistol and Revolver manual.
A net search will turn up lots of data as well. Hogdon's page has data. As does the reloadersnest.com page.
Brass and bullets may be a problem though. It uses a regular small pistol primer with .310" to .313" bullets. The brass is out there, but you may be looking at a special order from your local shop. If their distributors have any. Midway lists Remingtom brass at $99.99US per 1000, Starline at $110.99US per 1000 and Lapua at $235.99US per 1000. So at least it's still being made. Contact Epp's first.
