This one is really for the tool & die makers out there I hope some of them are interested in gunsmithing since this appears to be the only forum I can start a thread on. I don't have the opporunity to get on this site as often but didn't there used to be a tool & die forum. OK to the point I have checked the sites of suppliers for swaging dies for jacketted bullets but not satisfied with what was available so I would like to attempt to make my own dies to swage the jacket, core and then join the two. I'm going to assume that making a reamer for the desired length and ogive would be easiest however I have never cut curves on a lathe and have no idea on how I would then cut the flutes in a mill on such a shape. If you reply keep in mind I have zero training or experience in tool & die work all of mine is gun smithing and an odd part or fixture I needed to make a job easier.
