I've started back into loading in the last couple of weeks after a 20 year gap and took out all my old presses, hand tools etc. After reading quite a lot on this and other forums and old sets of instructions on using dies for both pistol and rifle shells I noted that most leave out the step of chamferring the inside and outside lip of the casing neck before insertion of the bullet and final crimp. Is this still a necessary step with the newer dies now made or are the writers/posters taking for granted that one is supposed to know to do this step automatically? Thanks...
