There's a guy that runs ads in Handloader/Rifle mags:

NON STANDARD
.30 to .50 calibers from Corbin equipment
Write for price list (deaf, no calls please)
Vincents Shop
210 Antoinette
Fairbanks, AK
99701

Never dealt with him but maybe some of our AK members have?

Does anyone know which manufacturers make .419 bullets? I do know that GScustom makes them but they print way high in my old 404. Open sights have little adjustability. Any other manufacturers out there? Thanks. "D"

Do you have a .419 bore, 404 Jefferys in which case it must be a European rifle...You probably should invest in a bullet swaging die set up and run .423 bullets through it...
