Re: 260 Rem Vs. 6.5-06
Another point (along the lines of air travel) is that coues and mule deer hunting in Old Mexico has become QUITE popular. If you have a rifle barrel stamped 6.5-06 and ammo that is stamped 270 win, 25-06 or 30-06 etc..., getting through customs is going to be a nightmare IF NOT impossible.
Just a thought.
Superior is such a subjective term.
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.
