Cast Bullet Data

I was stumbling around some gun sites earlier today and came upon the GMDR Low Velocity Chronograph Data. If you're a cast bullet guy, any page entitled Low Velocity screams Cast Bullet!

I've spent some time going through it, and I can see that this might be a heck of a resource. They claim that they shot upwards of 50,000 bullets getting the data. Some of it is really interesting.
