I can't see much practical difference, but it might be easier to fit the pointier AB/BT offerings in a 2.8" box in the .338cal. A longer Howa/Ruger77 box would not be so tight.

I've hunted with .338 NBT's at 2,800 in other chamberings and found them to be wicked mean on animals. Shoot 225gr .358 NABs in my Whelen single-shot at a lowly 2,450fps and they knock big holes too, while allowing a fairly flat trajectory for the velocity. Blood trails with both leave nothing on the table. The last deer I shot with that 225, I could see the gaping exit hole as the deer ran off. If it'll open at that speed on a lung-shot 125lb whitetail, it'll open on nearly anything.
