Does anyone have the dimensions and data for the .30 VVC?

I see it's chambered by Virgin Valley Guns and is based on the 45-70 case. The main problem (if you want to call it that) is that with a case head this large, you gotta keep the pressure pretty low; therefore, you ain't going to get much velocity - but maybe that's not what you're after.
