I want to reload my own ammo, but have never done it before. I don't know excactly what all I need for reloading. I know I need a press and dies, but what are the differences with dies and what are case plates and the other stuff I hear about that are needed for reloading. If yall could describe or explain the functions of the different dies and all that good stuff it would be much appreciated. Also what is a good starter press that would easily be able to be used once I become more advanced at reloading? I've seen that a lot of yall like the dillon presses especially the 550bs. Would the 550 be a good starter press.
