9.3x57 rim same as 9,3x62?

Are the rims of these casings the same? Or does the 9,3x62 have a 8mm Mauser case rim?

Do I need to alter the bolt extractor if I ream out a 9,3x57 to 9,3x62?

I'm sorry for these so basic ???s but I, so far, don't have specs on the cases, rim size, overall length etc, for these two rounds.

So for now: Are the rims on these two cases the same?

Thanks. Exit31

Same case as the 8MM.
