How Do You Work Out Ballistic Coefficient?
I'm trying to get ChainGunPro (or any ballistic calculator) to estimate windage specifically for my rifle. But whilst most of the required information is straight forward the variable of Ballistic Coefficient can make a massive difference to the predictions.
So how do I work it out for my rifle and pellet combination?
