You all are making my point for me. The major reason I get for using a smaller caliber is for "flatter shooting" When you look at the numbers that dog just don't hunt. I've heard my whole life about how flat shooting this cartridge or that is. Its bs, The trajectory of a 388 is not significantly different from the trajectory of a 270 out to 350 yards. Which one is the more efficient killer? There is no doubt in my mind that the 338 is far superior. For the gentleman that used sectional density as an argument, I think you need to do some research before you make statements.
