Help! I have been reloading 9mm for a few years, but things are changing. My son just bought a new bolt action in .223 and wants me to order dies to size and reload ammo for him. Starting out, I will be only reloading cartridges that have been fired thru his rifle. Was thinking about buying just a two die set with neck sizer in one die and bullet seating and crimping in the other. On the other hand, should I buy a three die set which will full length size. If I am confused on the die functions let me know. Anyways, any advice on what kind of dies(function) and brands would be helpful. I am also used to using carbide dies and no case lube, but from what I see available, that will have to change.
