Hello Clockmaker, RCBS does make dies, but I got a used set off E-Bay.
Be careful as E-Bay prices sometimes exceed the cost of a new set.
Bullets - Graff and Sons, I got the PRVI 85gr and they work well

Powder - I do not know what you have but a medium slow powder like Unique works well
There are a number of posts on loading for 30 Luger - all helpful
Good luck
