I can't speak for everyone (obviously), but I see an awful lot of "buy a reloading manual" suggestions as a first step, then "come back to the forum with specific questions" as the second step.
I think it is probably because there is a really good explanation of the reloading process, and equipment, in the start of these manuals. This can be 50 pages or so.
(What follows is necessary, but incredibly dry by comparison, reloading
data which makes up maybe 500 pages.)
It isn't really possible to summarize the material in those 50 pages in a forum format.
And all reloaders need to read those 50 pages...
So, wait until you can do that. All will be clear...
