Another rookie question.
I started reloading with some once-fired Lapua brass, but I have a limited number of cases to work with, so I ordered a box of new cases. Do I need to resize them before loading? Is the first fire relevant for accuracy, or do I need to fire them once before I can consider adjustments to my load development?
