no- he is saying-for example - an unfired 2 3/4 12 gauge shell will fit in a 2 5/8 chamber.
the crimped portion of the shell has to fit within the chamber when it has been fired - otherwise it opens into the forcing cone and there can be pressure implications
a 2 5/8 shell is 2 5/8 AFTER firing (or brand new before being loaded the first time)
