Neck sizing and full length sizing are options for cases fired in bolt action and bolt/lever/semi actions respectively. Assuming that your once fired brass will be reused in the same rifle then the Lee neck sizing collet die is very good when used according to instructions. It is a different technique than standard neck sizing. I have had accuracy improvement with .223 using that die.
It is normally recommended that new brass be full length sized before loading and shooting no matter the type of action.
