For those making 338 brass necking up or down.
What are you losing or gaining in thickness?
Thinking on a 338/06
Measurements if you have them please.
Parent case 25-06,270,280,06, Whelen
Starting neck thickness/formed thickness
Case length after initial size and after fireform.
Any other measurements you might have noted.
Notes from 338/08 would help if that was your project.
Thanks much
