If you're just getting started, don't need a trimmer, micrometer or deburring tool.

Avoid range brass if it's .40 cal. Might be from a Glock.

You can find a Lee kit for $100 or so that has everything to GET YOU STARTED. Lovingly hand-crafting every load comes later, unless you've got a lot of time on your hands.

Bullets, powders and primers....that's a whole different thing!
