Reference your favorite published dimensional drawing and it will reflect this as well.
Larry's question involved how you neck-turn a tapered case. I do it after sizing and the neck is a cylinder, but it makes fitting a headache.
2) How in heck are you getting a '06 case to form necks .0275" thick? thickest I've seen so far were only .0165".
If you loaded regular Swede brass in your gun and fit the neck like 45 2.1 says to do you could chamber a boolit with a diameter of .288"!!!!! A 7mm boolit would fall through the neck into the chamber. Most 7mm cases are only .315-.320" at the chamber neck!
I sincerely hope that was a typo.
