I used my lee neck sizer on some 308 brass for the first time. A slight peculiarity has happened.
Using the die, I can get a hornady .310 round ball to go completely inside the neck. And tension holds it in good.
And I can get a 170 grain .310/.311 diameter true shot flgc to slide ENTIRELY into the neck with no resistance or case tension.
A fired case only lets me get HALF the round ball to go in. And does NOT let me slide the bullet slide into the case mouth at all.
Should I be worried or should I be happy that I have easier time making round ball loads?
