[QUOTE="Bart B, post: 1135495, member: 5302"] jomp198q, Note that the standard shell holder height (base to top flat) is .125" rimless bottleneck full length sizing die shoulder headspace (yes, dies have headspace; dimension from the shell holder base to the reference diameter on the die's shoulder) when they're touching the shell holder is typically .005" less than SAAMI .338 Win Mag chamber GO gauge headspace of 2.1253", or 2.1203". The die set to touch the shell holder at the top of the ram stroke will set the fired case shoulder back to 2.1203" from the case head, then spring back a thousandth or two after it's pulled back out of the die. Your rifle's shoulder headspace in its chamber is probably somewhere between 2.1235" and 2.1253" [/QUOTE]
