Good reloading manual and stay reading, yes powder and bullets, I've been using everglades ammo but if you google there are plenty of places, brass is of course reusable so at some point of your using new brass when you go to reload it'll need cleaned, start reading through this thread from the beginning, belive it or not it's what got me started on this addictive path lol, I'm loading 9mm for around 8-9 cents a round depending on how many thousands of bullets and what discounts there are at any given time
