Re: Hard hitting, accurate load with a .308 168 grain berger bullet.
Whatever you can run with the powders above (safely) you can run faster with N540. Every bit as accurate as well. 2800'/sec+ is very easy with N540 under the 168's. I wont say how much + it is. You will have to work those up on your own.
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.
