I am in the process of stocking up on components for a 7mmWSM,I should have it back from my smith in a couple of months(he's building it off a 300winmag savage 110 action.).I am planning on shooting either a 162gr. Amax,or 180 berger,it just depends on wich one shoots better.I will be working with "warm" loads,not dangerously hot,but I will be trying to get as much velocity as I can get,safely.I am not looking for exact numbers on case life,just a ballpark # so I know how many cases to get for the next few years.
