I guess it all depends on where you draw the line at big. The OP asked about .338AX rounds, which, as I understand it, is a .338 Lapua Magnum, with a COL around 3.700 - 3.850. I reload .338-300 to a COL of 3.7765" all of the time with the newer style Forster Co-Ax.
That said (I just checked) the nose of a 300 grain bullet extends about 1/8" - 3/16" inside of the seater die AFTER the bullet is seated. I have not found this to be an issue (again, that's after loading a few hundred rounds) but it might bother someone else. I have to admit that the press is pretty much max'd out with the .338 Edge so if the OP is considering anything larger he's going to have to move up.
The older style press absolutely would not work (which is the reason that I bought the Ultramag press. I thought that it took up too much space on my bench but it's a hell of a press).
If I ever redo my reloading area I'll have a bench just for the Ultramag press and I would probably move my .338 reloading process to that. For now, what I do works for me.
.50BMG is way outside the range of the Co-Ax... and I have no doubt that the Co-Ax is too small for the Cheytek rounds.
