Just to give a visual for all viewers … the neck totally pancakes when a piece does give way and collapses …
interesting enough the actual neck OD is exactly the same as a neck that fully expanded and the shoulder didn't fail
** in this pic the .338 mandrel is hand seated in a fully expanded neck that didn't collapse…that "witness mark" is there simply to show where the mandrel stops in relation to the neck when hand seated on either a fully expanded neck or one that collapsed
again no issue going from .284 to .308 it's only when going from .308 to .338 this occurs … it's got me baffled
honestly the only thing different in each step is the mandrel … might have answered my own question right there lol
