I'm not an expert, but IMHO you really need to start with a single stage. You'll learn the basics that way. And safety!!!!!!
Later you can get a progressive.
You need to get with someone who already reloads to give you some basics. Got a buddy who does?
H&H offers a reloading class. Call them and talk to the reloading department. It's $50 well spent.
As stated above, I am getting back into reloading. Got 6+ years experience of competition long gun, & I reloaded for all my matches.
