Okay I finally got the RCBS 338 Lapua dies and the shellholder. Tumbled 50 cases today,lubed them and that´s it: The shellholder #37, new in the tiny plastic bag that says works for 416 Rigby and 338 Lapua does not accept my Lapua brass.Fired or unfired. Very funny. The stamps in the holder are correct too,well,my brass can´t read and simply doesn´t fit in. I wonder if I should return the $110 dies as well, takes forever to get a replacement anyway.
