[QUOTE="JBM, post: 74707, member: 1969"] [ QUOTE ] You could get a .6bc out of a pistol bullet if you could do your "testing and measuring" at a high enough altitude/low air pressure. [/ QUOTE ] I don't understand this at all. When measuring the BC, the density is not part of the BC -- it is a separate term. The only question is how different are the densities and mach numbers for the two different standards. At sea level, there is about 1% difference, less than the accuracy of the measured BC. [/QUOTE]
