Re: 168gr Sierra Match Kings for hunting?
Out to about 300 yards they work good. After that, at 308 velocities, they WILL NOT expand.
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.
