I got another question.

This is obviously an 8mm bore which the groove diameter is .323 and the bore diameter is .315 where in the world did they get 325 from. Did they just pull that number out of their butts? Why not call it a 323 WSM or a 315 WSM?

Sometimes I think ammunition designers have their heads up their butts half the time.

Yes I am just venting a little.
