and you dont come across something if you dont look for it...like poor velocity in a very accurate and great killing load..no chronograph = no problem

there is a very old saying in back country... a dead possum in the water tank isnt a problem untill you tell someone.

This isn't something I made up ,I don't require validation from a forum . I made the measurements at the time purely by chance as I was setting up my f/l die , which as it happened mirrored something I'd been told . Looking for it or not , it was measurable . I'm sure others have come across this and wondered why brass is suddenly a little tight to chamber.
Why would you think there's no squeezing on the case body as its sizing . The body will blow out during firing or do you think the chamber of your rifle remains steadfast resisting 55k psi of pressure without flexing and the case is a perfect fit ?
I'm not sure , but this appears to be angering you and that's unintended . It's just a forum and a discussion , its a difference of opinion, nothing more .
By the way love the analogy.
