Re: 20moa vs. 15 moa
In all seriousness, 5MOA at 1K = as posted already. 52.35" at 1K.
Like you said, it depends on how you interperet the question.
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.
