Does anyone use a name for the section of the rifle chamber between the end of the neck and the start of the freebore? I've heard *step*, *forcing cone*, and nothing else. Neither seems right, especially forcing cone... what does that little shoulder force? Every other part of the chamber has a well enough defined name. If it doesn't have one, it should. Maybe *neck step*, *neck shoulder*, *freebore step*, *throat step*, or ...?
