Re: .308 reloading info
RE-15, VARGET, H4895 (not too much, around 40-40.5 grains H4895.) For the 10 twist try the 190 SMK and RE 15. around 43 grains. But start lower. From a 26" BBL you should be around 2650. With the 10 twist and the high BC it will do amazing things at great distances. If you are stuck on the 175-178. I 3rd the statments of 45g. VARGET.
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.
