To start with, get a set of Lee dies. Later on, when your needs evolve, you can add dedicated dies to the set, like a micromemeter seater, body die, neck sizing die or a neck bushing die.

At the start, a new Lee die set for your caliber is perfect. Of course, if you can get a used set of any make at a better price, do it.

Make sure you have the right shellholder for the caliber you want to reload, for your press.
