probably see a minimum of a 40% greater barrel life than the .243 case if that matters much. A 6HLS will do everything you want I might add. The 6x47 is easier to bet brass for. You could also chamber a 6/250 AI off a 6mm Ackley reamer headspaced off a 22-250AI gauge, and simply use generic .243 brass (cheaper to come by). That round will drive the 105 grain amax to about 3000 fps without too much trouble. Should also see a 2000 round barrel life as well.
