Is there a gauge or method to address the following problem?
I have a semi-auto .308 and I discovered that even after full-length sizing the cases they would not fully chamber without forward assist. Of course after full-length sizing they clear a case gauge, but that just confirms headspace and OAL.
I assume that the remaining problem is that at some point along the case body the FL sizer isn't squeezing the diameter down far enough for this particular chamber. Does that sound like the reasonable/likely explanation for the sticky chambering?
If so, how does one determine whether the gun's chamber is excessively tight or whether it's the FL sizing die not fully squeezing the case bodies into spec? Or what's the best solution?
