OK I am bitten by the bug (neck turning one) and was wondering if there is a place to go to get exact specs for neck sizes for 7x57 and 8x57 MM brass?
I make them from 30/06 military brass.
Looked in cartridges of the world and the neck sizes they give are already thicker than the brass I have made!
Makes a guy wonder sometimes.

Re: Neck turning brass
It is determined from the spec drawings; either SAAMI or CIP.beekeeper wrote:OK I am bitten by the bug (neck turning one) and was wondering if there is a place to go to get exact specs for neck sizes for 7x57 and 8x57 MM brass?
Here you go: http://www.saami.org/pubresources/cc_dr ... Mauser.pdf
It is the neck diameter (.3207) minus the bullet diameter (.2845") divided by 2; or .018"
For the 8X57 Mauser: http://www.saami.org/pubresources/cc_dr ... Mauser.pdf
