All of the above is good advice. The only thing I will ad is that I never, not ever, resize a case without having the firearm there to check the sized brass in the chamber. I size a case down until there is a little resistance (in a bolt action) then screw the die in just a little (.001-.002) more. You can check how much you are setting back the shoulder with a caliper and appropriate size socket or or a dedicated tool if you want.
