Re: Searching for 30 cal. with with Rigby head size
By more user friendly I take it you meen better barrel life and being less finicky. Most other 30 cals with that size base will offer the same temperment. You may look at the Lazzeroni 7.82 Patriot. This is a short magnum with the same size base.
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.
