I am no ballistics expert. That is why I have engaged one in this project, but let me take a quick run at this.

There is no doubt that any bullet of common BC fired at the same velocity will impact at for all intents the same point and at the same time. There is also no doubt that if you take these same bullets and increase their SD without changing their profiles, the BC will increase.

What we have to understand is that the BC is a function of profile and mass. For a given profile if we increase the mass, we will also increase the BC. A longer bullet that is made lighter will suffer a decrease in its BC, and therefore will suffer downrange.

There is a tradeoff here that has not been entered into the equation. A longer lighter bullet may suffer a decrease in BC, but it will also be fired at higher velocities. The jury is out on which one will be more accurate. BC does not mean accuracy and neither does SD. They work together in the optimum bullet design to achieve the best results from accuracy and retained energy fired from a proper weapon.

I am excited to get to the range with some of these bullets and do some testing. We will be doing a lot of these calculations in the months to come, and I want you two guys doing some of the first shooting. I appreciate your passion.
