The thickness should be
(whatever your chamber size is (cast and mike it out) less the bullet size (0.308) )divided by two (two layers) less the tolerance you want to live with
confused? me too.. cant write formula here
I am using about 0.013" thick neck and that gives me about 0.005" tolerance on my bolt gun.
If you are using it in a semi/auto guns, better get about 0.008 or more tolerance.
