Let me suggest getting a set of LEE dies.. they are a quality/economical set of dies that you can FL size or neck size.
The main issue between full length and neck sizing generally is consistency and brass life. You should FL size ANY brass you will use the FIRST time through a particular rifle. After that, you can neck size only – neck sizing only allows brass to form to your rifle’s chamber and create optimum headspace. I don’t mean to sound like a lawyer but buy a reloading manual (Sierra or Nosler for ex.) and read through it, I did and became highly enlightened..
