I have a few friends in the range that have reloaded for years and they may be my advisors since I have not much experience in this. But anyway I would like to hear some other opinions about it.
Buy a reloading manual- A lyman's 48th edition is a good one- read the reloading instructions 3 or 4 times.
Ask one of your friends to if you can watch them reload, being able to see someone else do it and show you how will put you a long way ahead in the learning curve. Ask lots of questions- and remember no two reloaders seem do things the exact same way or even favor the same tools.
Go to a stationary store and buy yourself a laboratory notebook or two to keep notes on your loads. I have about a dozen loads that I typically use and can remember off the top of my head, but I always double check what I'm doing, and log what I reload.
Only reload one cartridge at a time, and keep only the components for one cartridge on your bench at a time. Be absolutely sure of what you are using, especially powder. IMR 3031 cans look an awful lot like Goex cans. Yesterday I was loading up two different cartridges that required RL22 and RL2400, And I had to double check to see that I had the right powder can on the bench.
The RCBS starter kit is probably the best way to start out with. They aren't the cheapest, but will last a lifetime, and you won't have to scrounge around trying to buy seperate, cheaper tools, without knowing what to get.
