Can anyone tell me the bore diameter, groove diameter, and bullet diameter used in a typical 8 mm such as the 8x57 Mauser?

I was under the impression that the bullet diameter should closely match the groove diameter so the lands make a good impression and good gas sealing is attained.

In addition to the info from Vibe, there is also the older 8x57 which is .318" groove and .307" bore.
