I have had several of both.. For me the .338 is good, but no better than the .300.. Not nearly as flat either.. With the modern bullets we have you can shoot a 150 in a .300 for super flat traj.. If a guy were in deep timber like northern Idaho or Ore. The .338 would be fine especially with heavy bullets... Otherwise the .300 is more of an all around rifle... I have shot a number of elk with the.338 and the .340.. Both kill well but no better than the .300... For a time a bunch of my shooting pals and I went the ,338 route.. After a couple seasons , most either sold them or stacked them in the safe.. Here there is much, much open country elk hunting and it was far easier to hit and elk with the .300 across a canyon with the .300..
