Re: Berger and barrel twist
Berger is an advocate of spinning a bullet as little as possible and still have proper stabilization. This will lead to the most accuracy potential. Can you run 150's in a 10x? Yes. Is it the best possible combo? No. That is not to say that it wont work well. 10x's in 30 cals are best used with 220-240's and several all copper bullets but will work with any other bullet weight.
Long range shooting is a process that ends with a result. Once you start to focus on the result (where the shot goes, how big the group is, 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.
