Wait 'til next year Daryl. Dollars to doughnuts they bring out a .375 on that lovely shortened and blown out .404 Jeffrey case. Should not be much better than the .375 Ruger though.
The .338 Win is a great cartridge and I have owned one and also a .340 Weatherby but did not care for the rifle. With these two and the new .338 Norma, .338 RUM, the .338 Lapua and the mighty .338/378 Weatherby as well as the .330 Dakota,and now the 33 Nosler, the magnum size cartridge in .338 caliber is well covered by the industry.
Though I own and love the 9.3 caliber in the 9.3X57 and 9.3x62 formats I cannot see the use for a wildcat 9.3/33Nosler especially since most African countries would not allow it for DG. Also the 9.3x64 is a very nice over the counter beltless case with enough power to drop the biggest bear.
I doubt a Moose or brown bear would agonize over .009" of bullet diameter when hit with two and a quarter tons of kinetic energy. But then again if it weren't for the experimenters we wouldn't have such useful cartridges as the .14 Walker to shoot mice at 200yds or 26lb 4 bores firing 2000gr bullets at $150 a pop.
