Re: .308 Question
I have seen guys use 700 LA with the 308. What I dont know is if they were using them as single shots or if they were useing em as repeters. As posted already, there may be some feeding issues.
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.
