neck sizing is easier on the cases, meaning you will be able to reload them more times and you dont have to use lube if you are using carbide dies. But you can only use neck sizing if the cases were fired from your gun, and after loading will be fired only in the same gun. You cant take brass fired in one gun, neck size it and fire it in another, because when the brass is fired, it fireforms to that specific chamber. I only have one .308, so I use neck sizing only when I reload. If I were to pick up range brass, I would have to full length re-size the first time, then I could just neck size after that. My dad has two 30-06 autoloaders, since its tough to keep the brass separate between the two guns, he has to full length size all of his brass.
