ok, start with your die up high, lube the case well start resizing, watching the progress as the neck gets smaller farther and farther down, when you get close to the neck/shoulder angle junction, start trying it in the gun, when you can feel just the slightest resistance as you push the bolt handle down, then screw the die down 1/8 turn and lock it down, your die is set for your chamber and you get the best possible case life.
Now neck your remaining cases down.

This strategy should work great.
