Re: Target crowns
If a recrown doesnt help, maybee try 168 and 175 SMK, 178 AMAX, RL-15 or 4064IMR along with federal gold medal match primers and lapua brass. Also 1 thing that might make a huge differance is 2.825-2.830" OACL depending on what your magazine will allow. 2.825 will work for sure and some BDL's will allow 2.830".
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.
