[QUOTE="Michael Eichele, post: 170031, member: 1007"] There are calculations for a general BC number that will get you close in some cases. The calculations are complex due to the need for an accurate form factor. Youre better off using calculators made for calculating BC's such as those found in most ballistic software and some online ballistic calculators.Then there is the real world. The best way is to develop your load and then go out and determine your true BC by real world firing tests. Sometimes you will find they are spot on or very close to published and other times you will find they are way off the published number. The best manufacturers can do is give you a "mathematical" estimate and an average. This number will be close for "average" circumstances but could be vastly different if you launch them at higher than normal speeds or lower than normal speeds, spin them too fast or are stabilizing them by bare minimum standards and many other factors which is why it can be labor intensive for us LR types because we dont use average equipment. Load em up and get out there and shoot em. Use the factory BC to start and make the needed adjustments to your software when they impact either higher or lower than the software tells you they should. [/QUOTE]
