Re: crosswind affects drop
I am not actually 100% up to snuff on this subject. It is another issue I have been needing to research a bit further so take what is said here with a grain of salt.
Here is what I do know. I know that the principal of what he stated to you is true. There is a verticle component with crosswinds and not just horozontal. I have bever been led to believe nor have I seen so much effect that it equalled 1/4 of the horozontal component.
Maybe GG, 50, Carlock or Litz has a more educated answer on the subject.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
