This (these) could be the next oncoming thing in bullet technology. I could be wrong but I believe that these bullets are electroplated in that the core of the bullet is immersed in a conductive solution as a cathode and a copper or jacket source is an anode and the copper is transferred or plated (attracted) onto the cathode. I think (again I ask for a correction) that this is not a new idea I think that Speer Gold Dot bullets and the old Remington Power Lock bullets were made the same way. In my thinking this would eliminate much waste from making bullets using punched cup, core, and swage methods. Possibly some bullet tech having more knowledge on this subject might make some comments. As I remember using my .22-.250 I was able to get super good accuracy (like one hole 5 shot groups) using the old Remington Power Lock (Loct?) bullets and they were either 53 or 55 grains.
