I found this two part article sums up reloading pretty well. It encompasses a multitude of information I had questions about too.
I still haven't decided to do it or not but with the recent fervor for gun control coming from some republicans I'm going to guess ammo prices will start to see demand again and prices go back up. Especially nearing 2018 if we are looking at a Dem blow out in congress.
When ammo shortages occur so do shortages of reloading components.
