We had discussed about use mandrels after the resizing the brass to uniform the bullet seating.
I was doing this now on new Lapua Brass (unfired) and have noted some brass I needed to use less effort to introduce the mandrel so I assume those brass will have less neck tension too.
How do you deal with?
Shoot the ammo and separated the brass which have the same velocity?
