Have a good look at the stickys at the top of this forum, then get a good reloading manual e.g. Lee, Speer etc. and get to understand the process. Then talk to 1967Spud on here. He has a very good reputation for excellent service and good prices. He also has a stock of used kit. I have no connection to him other than as a customer for a set of dies.
Enjoy the journey. Best wishes.
