Wow, all I can say is Wow!
CourtenayBoy, I think you are getting some poor advice.
first off, think of what YOU do for a living, and then think of what your advice would be if someone with no experience asked about your job!
Want to be a Surgeon? Easy, grab a sharp knife, some needs and fine dental floss! Start cutting!
Want to be an Air Traffic Controller? Easy, just pick up a mic, and start telling aircraft where to fly.
After you kill a few hundred people, you may sit back and rethink your whole plan.
when I started reloading for 357mag, I started single press, and used to load 300 in a sitting.
it is obvious to me, that because you are asking, you are not ready for a progressive setup. You need to learn the basics.
Lee Loader? Sure, I have 25 of them.
single stage? Great, I have 3 of them.
Casting is a whole 'nuther world.
things like the LEE factory crimp die can totally ruin your day if used improperly, and you won't know why.
You WILL be able to sell your used press/dies/etc for near what you paid for them then upgrade as you progress.
but if you were starting off in the trucking industry, would you buy a 600hp Pete, and load up an 80,000SuperB before you even got your license?
regarding your list:
you have no bullets, no bullet mould, no lube, no loading blocks, no dipper, no loading manual etc....
first things first
get three or four reloading manuals, then get Lyman 3 and lyman 4 cast bullet manuals.
Then READ them
get the supplies you will REALLY need after understanding what you need.
get a simple Lee setup Cpress/dies etc.
make a few thousand rounds, and learn to make them perfect.
THEN upgrade, and sell off your old stuff for near what you paid for it.
I'm not trying to be a Ahole here, but this is exactly what was told me when I started off.... and it was good advice back then.
have fun, be safe!
