If you are asking about bullet moulds for casting your own, then RCBS, IMO.
If you are asking about a commercial casting outfit who is selling cast bullets, then it is Leadhead Bullets, Inc., St. John Kansas. As far as I know, they are the only folks claiming to be selling bullets of true Elmer Keith design. They look like true E.K. bullets in the photos.

I would like to be proven wrong about this, but every other SWC I've found for sale out there has a short nose and that blasted bevel base. No true E.K.-designed SWC bullet has a bevel base.
