Mine is a 6mm-250 which was named 6mm Int'l. Based upon the limited research I've done, I think (but am not certain) that the cartridge that Savage 99 is referring to is the "Walker" version of the cartridge. It is a 6mm-250 with the shoulder sharpened to 30 degrees and bumped back a hair to create a longer neck, thereby also decreasing case capacity.

Mine is a 6-250, so your numbers are a reliable guideline for me.

Thanks again guys,

PS- I see, after actually inspecting what Savage 99 put up there, that his "Remington Int'l" has a 26 degree shoulder... there are many, many iterations of this one...
