.338 Win Mag.
250 Grain bullet for most kills. There was a few years that I used 185 grain Barns X, then later switched back to the 250 Grain. The 185 Barns X seldom had an exit hole but I recovered a lot of bullets just inside the skin on the other side. They always performed flawlessly as far as weight retention. 250 Grain Nosler Partition or Bonded Core always have had an exit hole so I don't get to recover them. 250 Grain Sierra Boat Tails have had an exit hole about 50% of the time. They typically break up when they hit bone but they do a lot of damage even if they don't exit. I have also used the 250 Grain Hornady Interlock and they perform about like the Sierra Boat Tails.
I have also taken elk with my .44 Mag Ruger SRH. 317 Grain hard cast gas checked bullet.
My .338 Win is an early model Ruger Mark II. Last year I upgraded the old boat paddle stock to a free floated walnut stock.
My experience with elk is "Use Enough Gun" :-)
