I believe there has been some mis-information here. The bullets and casing that were pictured here were prototypes from early in the supercollider experimentation. At the time, there was no microscopes available to actually photograph what happens in a supercollider collision. Instead of working in a microscopic scale that could not be documented, it was decided to start with a macro scale experiment to test the viability of the microscopic supercollider. They began with the aforementioned wildcats and worked their way to the .50 to .17 BMG neck down job. The .17 BMG was fired from a 6 ft. barrel that had an outside diameter of 8": a bull barrel to say the least. Some work was needed to keep the actual bullets from ripping apart because of the extremely high velocities. It was decided to used a milled brass bullet...
Come on. If you've read this far and not figured out that I'm full of excrement, I have a lovely bridge in Brooklyn that's for sale.
You should go back to your OLD avatar (No matter how cute your daughter is ) and give a guy a reminder.

I know squat about "super colliders" I WAS wondering how they aimed the bullets at each other though.
