I do have brass to spare. You can use .460 Wby cases for US use, but getting 100 for use going to Africa is what I would recommend. I could sell you them for $3 each.
The project is nearing the top of the project list again. Lots of drama I will spare you, tied to my time in the service. It appears to be clearing out now, so I should be getting to it soon. Have been focused on a barreled receiver I purchased from the CMP on 2003 and am now finishing the stock on it. It is a re-constructed parts rifle, but it will be a functioning example of an M1917. Also restored a bubba-ized M1916 just to get a functional .30-06 up and running - put a nutmeg laminate Boyds stock on it in place the 1950s Ward Cleaver white spacer, plastic black fore end tip monte carlo stock. I need to open up the space for the Timney trigger on that one and it should be done for this phase. It needs to have the metal re-finished at some point.
Have wrestled with a 7mm-08 on a yugo-24 mauser action as well.
Also, the .375 Ruger gets ALOT of my attention, so that has slowed the work on the .495 as well.
It is bubbling up the hit list though. Great situation to have several projects to work on at once/in sequence! I have slowed down as well due to funneling the vast majority of the $ into Namibia next SEP, assuming WWIII doesn't kick off, our 2nd civil war, etc..
