I would recomend gauging the neck of a loaded round and then gauging it after firing and
then deciding based on your chamber dimensions.

Also mic. the neck wall thickness of the fired round and the Norma to see if there is any
difference . Buy a box of brand x ammo for break in and this will save time and money
and get you started right with your new Norma brass.
