    I'm adding up the cost per round to start reloading again with a .308 this time. Plan on standard pressure manual loads with 180 bullets.
    Yes that is neck sizing only. Full length sizing would reduce life for sure. The softer brass requires more frequent full length sizing to prevent a hard bolt close. To maximize your brass life while full length sizing you should size it no more than you have to. Pull the firing pin from your bolt so that closing the bolt does not require any force to cock the firing pin. Then back out your sizing die so that you’re barely sizing your case. Now try it in your gun. You’ll encounter resistance trying to close the bolt. Turn the sizing die slightly and repeat the process. As soon as you can close the bolt all the way with only slight resistance, lock your die in place. Now you’re full length sizing without over sizing. You’ll probably split necks eventually before you wear out your brass if you aren’t using a bushing die or annealing your necks.

    Sizing this way would I need to fire through new brass once before I work up loads with it?
