I don't think you need to step up in powder capasity to step up in big game performance. I also don't think the 338 Win mag will offer you much over what the 300 does as far as on game performance goes. What one can do with a 338 so can another with a 300.

Personally, I'd probably look at a big bore lever action like a .444, 45-70, or 450 Marlin. If you want a bolt action I might look at a 35 Whelen or 350 Rem mag.
