I'm new to the Dasher and just recently acquired one. It is a .265 neck. It came with some loaded rounds, prepped brass and some fire formed brass. The necks have been turned down to the br's shoulder. With what I've been reading I planned to only turn down far enough to create a false shoulder then fire form. The way these are turned the 'thinned' brass extends part way down the fire formed Dasher shoulder... any issues with this?
