Lee Classic Turret kit and dies from FS reloading. Gets you a manual to start and you will need the case length gauges for each rifle calibre (don't bother for pistol) to use the kits trimmer and a digital calipre to measure case and ammo lengths. Later you can pick up other manuals and a different scale if you don't like the Lee. Save the tumbler and other fancy tools for later after you have a good foundation of loading experience.
All you need to do is wipe clean, size, trim (or check if needed) debur, reprime, measure and charge powder, seat new bullet. Many other processes and their tools are optional if you need or choose to do them.
