What Groove Diameter for a 9,3x62 Mauser?

I'm having a Vz-24 rebarreled to 9,3x62. My GS will obtain a Moly-chrome barrel in the rough and do all the work. When we were researching the specs, we found the original 1905 cartridge used a 0.365" groove diameter but the bullets available today run 0.366"!?

So....What bore and groove diameter do you used for a 9,3x62 Mauser today?

FWIW, Half Moon Rifle Shop still makes their 9.3 blanks with the original German bore and groove diameters. They shoot .366 bullets as well as any other.
