Ya don't need published data to shoot it...it's nice but not mandatory.
I like the Weatherby offering 20 or 22 inch barrel, at Buds. Probably buy the 22" for me.
Buy a couple boxes of factory nickel plated cartridges.
Make some dies on the lathe.
And load the fired cases.
As you now have actual case H2O cap, and bullet length, COAL, all the parameters ya need to load this cartridge. Plus factory fired ammo from your chamber to compare.
So one can be shooting and reloading this new cartridge in a few days, with a little ingenuity and lathe skills.
May be able to rework existing dies with carbide tools and polishing, once you have your fired cases to measure.
