Re: 225 Nosler and 338 Lapua...anyone?
Not using the 338LM but the 338 EDGE. Very similar case capcity/ballistic performance. I have ran the 225 AB using 91.5 H1000 with the fed 215GMM primer. Sub 3000 FPS but scary accurate.
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.
