Re: bad primers help
I have had similar problems with CCI primers. I havent used them in 10 years because of that. Couldnt tell you how they are today.
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.
