It doesn't match the G3G numbers, but it doesn't have any discontinuities and its's pretty close.

Thanks for this. :)
Added thought: it occurs to me, that if you have weight of bullet and density of bullet, that volume of bullet can be determined, and that once you have volume, the aspect ratio can be estimated based on that. Doubly thanks to you and Doug for that.
