Re: signs of pressure
Sounds like it could be 1 of 2 things.
1: A different lot of powder.
2: A slightly worn (erroded) throat. This will cause friction on the bullet driving up the pressure.
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.
