Thanks for the proof comfirmation Raimey.

I have dies from CH-4D and we tried a sized case. The measurement difference between the chamber and the resized (or factory S&B) is .007 narrower just below the untapered area leading into the neck (which is about .380) It would have been great if the factory dies would have bumped it down far enough but not so.

I agree that as long as everything is true, the full sizing can be a one shot deal and after that it is all in the neck if using reasonable loads.
