Thanks for all of the responses!
Yes, yes, yes...No, fireformed cases are different than new cases, and same holds for FL sized new or FL sized firformed. They're different, they springback differently.
Most productive is fully fireformed -unsized(closest fitting to actual chamber).
Then you could FL size and measure again if you like. You'll probably cull some more with this.
