[QUOTE="MAD10, post: 2874754, member: 29370"] 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 [ATTACH type="full" alt="IMG_0208.jpeg"]483255[/ATTACH] [/QUOTE]
