Thread: Newby reloading question. Tight bolt cases

Depending on the chamber the original brass was fired in, it might not be able to be sized down enough, diameter wise, to fit into your chamber after it springs back.

This the issue with brass fired in one chamber then put into another, small base dies will generally fix it

FWIW Lapua brass is a better bet in the 338 Lapua Mag than Norma if you want top performance.
