I FL size virgin brass. Most go nice and easy, some need more effort. First firing is fire forming anyway. 2nd firing and on are neck sizing and become "working loads".
FLS, check OAL, trim if needed (doubtful) and chamfer to your desired angle. Manufactures have good/great quality control, but it is your rifle and does not take much time to be sure.
