After shortening or necking down a case to make a " whatever " wildcat, what should be the wall thickness of the neck brass to achieved sufficient pressure on the projectile ?

It depends on you reamer. You obviously dont want to go too thin but on my last wildcat I had the case neck thickness of .016

In big bores, I have seen down to 0.012 and up to 0.019 for smaller cases. When fiddling with a new design, I use 0.014 as a rule of thumb
