Frank sometime back I saw that question asked on a metal working site.The guy worked in the field and did the math. It takes a LOT of pressure to form annealed copper into a bullet shape and then you'd have to drill out the nose to get some kind of expansion from them. Most of our reloading presses are "cast" iron or Al today so don't think they'd take that kind of pressure. I'm sure someone Varmint Al could do a stress analysis to show the force needed.
