I was thinking about this and the question came to mind. Is figuring BC based on trajectory only taking into account the BC from the point where the bullet and scope are zeroed out? Should I be trying to look at it as total drop from the muzzle to range b and c to find a BC that isn't infuenced by scope hight or zero range and height?.
BC isn't influenced by scope hieght meaning that changing scope doesn't change BC. But changing scope height can make 2 or 3 set's of groups more closely fit a particular trajrctory or a range of trajectories.
The more data points you look at from muzzle to down range the better your conclusion will likely be. And the more times you repeat it, the more conclusive it will be. Repeatability is key to making reliable conclusions.
