Problem with Norma brass 243 win.

Got time to work on brass, after reading post, (thanks to all that responded) I had to set shoulder back more to get it to work. All brass started at measurement of 1.629, Peterson, Rem., and Federal all worked at 1.6265, the Norma had to be set at 1.624 for it to chamber and bolt to fall on its own. To answer a few other questions: the mandrel is .241 and the necks are 1th larger on Norma brass and I do have the neck turning set-up.
