Just got my 1st box of .308 Lapua brass. Are the necks on these already sized for loading? Mine measure .335 to .336 outside neck diamater. I was going to size them using my lee collet die before loading but they are tight going into the decapping stem/manderal of the collet die.
So should I size them anyway? Some of them have dents in the necks. I thought about expanding them using my K&M expander then sizing them with the collet die, but that would put extra wear on the brass. I may just push them through the collet die; the maderal will expand the necks just a little and iron out the dents. any thoughts?
