Lowest SD of Weight Per Sample Size

Cost

Cost per round from Common Available Quantity
Lowest SD of Diameter for the Money
Lowest SD of Length for the Money
Lowest Delta of Diameter (Sample Averaged) per Bullet (Concentricity) for the Money
Lowest Delta of Length (Sample Averaged) per Bullet (Concentricity) for the Money
Lowest Weight Delta (of Total Samples) for the Money

Bottom Line

3D-Graph of SD-Length, SD-Width, SD-Weight, With Cost written at the top if possible.

Note: I am not sure how the extreme freezing or heating will effect bullet hardness, someone might want to test this in the future....hint..

I would also like velocity tests as it correlates to diameter and temperature.
