10-4, I'm just going off Youtube Tutorials...
That is how I started too.
If I where to start all over again I would start with these and never look back.
-Get stainless media and a rock tumbler for cleaning your brass
-get this powder measure and google how to fix it for more accurate results: http://www.cabelas.com/product/rcbs-reg-chargemaster-combo/741110.uts?destination=/catalog/product.jsp?productId=741111&categoryIds=104792580|104761080|544895280|
-If you plan on reloading more than one caliber get a Forster Co-Ax press.
Those three things will cut your reloading time/setup down a huge amount. The difference between spending an hour setting up your powder measure vs 5 minutes. Or an hour dialing in your seating die vs 5 minutes etc. If you tumble your brass in walnut media it will come out very dusty and you have to spend the time to wipe down each piece with a rag vs the stainless works better and you leave it in the sun or toss it on the stove for a few minutes to dry.
Yikes that powder measure is pricey! More $ than my press.....
I don't want to a progressive reloader and one by one sounds brutal too., so I opted for a RCBS Turret press. That way I just buy a turret and set up the next caliber if the Turret I have is full. But I should be able to get two calibers out of one turret. It makes sense in my head....
I haven't picked up a powder measure yet, if I go with your suggestion it might be a minute lol.
