I am no expert, but I have been reloading since the late '60s.
I don't load near as many different calibers as I once thought I needed to,
and I don't reload everyday, but I have always attempted to stay current
with any new info, and I sometimes build a few just to stay in rhythm.
If I have learned anything worthwhile to pass on as solid advice, it would
be
THE VERY FIRST STEP for anyone, for everyone, that is interested
in getting started, [and I can't stress the importance of this enough] to
purchase one or more reloading manuals and read everything in it prior to
the actual caliber by caliber load data info. When you get finished, read
it ten times more. Read and re-read until you know it
AND understand it.
You don't have to buy 2 or 3 'current' manuals at $20-$40 each, there is basically
the same info in the older editions that you can by on e-bay for a significantly
reduced [cover] price.
My opinion is a Hornady manual has the best reloading info basics and explanations
with Lyman following, although any are viable.
I also recommend "The ABC's Of Reloading" by Rodney James
www.amazon.com/The-ABCs-Of-Reloading-Definitive/dp/1440213968If you don't think this advice is worthy, then I don't think you are safely ready to begin.
Reloading is not rocket science but it can be dangerous, or even deadly.
I can reference 100's of situations where others wished they were aware of
THIS FIRST STEP.....before their mishaps.
Be a good Boy Scout. Be Prepared. Be Safe. Have Fun.
