I just pulled a factory Lapua .338LM 250gr Lock Base and had never seen a bullet with this ... sprue? ... in the base before. What is the purpose of this design?
My best guess is that it's like an open-tip in reverse – i.e., the jacket is drawn from the tip to the tail. So it saves the trouble of pointing an open-tip? Or does it have some other purpose or advantage over OTM profiles?
