I looked around for one last summer, then thought of building one, but I went with the .338WM instead. Lots of them around and you can load it down if recoil is a concern. I really don't know why more manufactures don't chamber for the .338-06, I think its a great loading for all around hunting.
FWIW for the $$ it would cost to build one on a M96, you could buy a stainless .338WM Savage, Ruger, Tikka, Browning or Rem XCR for less. I'm not saying the magnum is a better cartridge, just a lot cheaper.
