steyrsteve10.75 or .416 on 8x68S case? .40/240 Weatherby?
Every once in awhile I get a Jones to have a 10.75x68 put together. But brass, last I checked, is hard to find. So I was thinking (smells like tires burning!)would a 10.75 (.423) or a .416 on 8x68S brass be a viable alternative?
OR...
Has anyone ever put together a .40 something using .240 Weatherby brass. You get 30/06 case capacity and can use a 30/06-length action. You avoid the hassle and potential problem of the non-shoulder rimless .40 something/30/06 layout (purists of the 10.75x63 genre can turn their heads). Any thought from any pioneers?

igorrockIf I remember correct, CH4D sells reloading dies for .416x68. I have one .416 barrel blank spare and has been thinking to do something with it.
Most known wildcat ammos based to x68 case are .375 Hölderlin and 8,5x68 Fanzoj. The first one even has a C.I.P -status.
Wikipedia has good text of 8x68S and it´s wildcats:

boom stickLook up 425 Fossdal. .423 bullet on a belted 06 case head for 06 size actions. Headstamped brass to boot. I do like the idea of a 10.75-8x68S aka 10.78x68S for easy barrel and headstamp nomenclature conversion.

Big Wonderful WyomingThe Swiss have several 10.3 wildcats based on the 400 Jefferys, 9.3x64 and 8x68 Schuler.
Some Swiss Cantons (canton= state/territory/county) have funny rules about only hunting with calibers above .400. So a lot of them get around that by shooting VLD light for caliber bullets in elephant guns. That we they are not crippled by the 10.3x60R and it's Edwardian era speed and power.

sroseUse a Remington RUM case which might be easier to find than the others.

AtkinsonIve owned and shot a number of 10.75x68..Its really a decent cartridge, and equals the early 404 loads that made that caliber famous..a 350 gr. Woodleig at 2350 FPS and a 400 gr. at 2125 FPS..and on a small compact rifle that can hold as many as 5 rounds. I'm not sure any of the other wildcats you mention has any pluses. We have the 416 Rem , the 416 Ruger, on magnum cases. Just seems to be a study in futility, as are most wildcats today..Methinks the wildcatter is pretty much been tossed under the buss, he has no place to go so he must give up all sinseabilities and become entrenched in his endevors as a copy cat.

Ray ; Very eloquent. However. Since the 400 Whelan has been wildcatted a LONG time ago. It is not a new endeavor. It is a truly intelligent and useful round. . To the OP. The 400/240 Whby, while just fine in it's own right was only created because of some reloading dies that were cut with a reamer that had an under spec shoulder diameter. With all the work M.Petrov and R.I.P. put into the 400 Whelan recently. The 400/240 is something of a exercise in futility.
The 400 Whelan/Petrov/Berry, 411 Hawk, 400 PDK, ect. All prove there is plenty of shoulder for 100% reliable headspace for ignition.
Phil Shoemaker : "I went to a .30-06 on a fine old Mauser action. That worked successfully for a few years until a wounded, vindictive brown bear taught me that precise bullet placement is not always possible in thick alders, at spitting distances and when time is measured in split seconds. Lucky to come out of that lesson alive, I decided to look for a more suitable rifle."

AtkinsonI am sure they all work just fine, most wildcats do, that was not the question IMO..the availability of 10.75x 68 brass today is not what it has been in the past, but its always been around if you know where to get it, Horneber being the best I've used..I always felt that the 9.3x338 Win would be the best

option and moreso today than in the past, as all brass seems to be drying up, and that should always be a consideration in wildcatting IMO..I only state my opinion, I'm not a caliber cop!f Going back to the 1950s I used the 400 Whelen on an old springfield, it was a great caliber and had plenty of shoulder, today I would probably opt for the 9.3x64 or 62 case..The metrics and foreign brass has become more available than domestic brass..WW and Rem have pretty much dumped on the American shooter and will not be making brass for the next 3 years and more profit is in selling loaded ammo. That came from the top.
