I'm been the primary guy running and programming our Star swiss lathe at work. If you could get the material cold rolled or ground to size, I bet with the right program you could be getting a less than a 30 second cycle time. there are so many variables doing such a thing but with the right tooling you could flat crank them out. The only other faster way would probably be with a screw machine that does several bars at once.
About 4 hours south of me is Blunt or ATK or whatever they're called now and they do Speer bullets and I think CCI, I'll have to check some ammo, but most all of there stuff is cold formed in high volume from what I've heard. From my little bit of shooting most of there stuff is top notch. Manufacturing this way would lead to very high output levels in the size of operation they are running just in the one location.
