A friend and I are both having problems keeping our seating depth of our bullets consistent. We set our seating dies and seat a bullet lock it down and the next bullet might seat .008 different from the previous bullet and it continue's to change from bullet to bullet. We are both loading Berger VLD me a 7MM Rem Mag 168 GN and him a 300 Win Mag with a 210 gn. Is anyone else experiencing this kind of seating problems? Any help would be appriciated.
