Ever wondered how a modern, jacketed bullet is made? Thanks to Berger Bullets, here’s a short video clip that shows how bullets are crafted. In this short sequence filmed at Berger’s factory, you can see machinery that forms the jacket, inserts the core, and then forms the final shape.

If you’re curious how this beast works, Alan Slocum posted an explanation: “It works kinda’ like this”, referring to the photo below. Sierra’s big machine uses a horizontal hydraulic ram instead of the push-down yellow Play-Doh lever, but yes the basic principle is the same.
