Re: stabilization question
My experience is that if they punch round holes at 100 yards then they are stable. Thest them at 300 and if they are still straight, dont worry about it.
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.
