[QUOTE="woods, post: 968383, member: 6042"] Forward movement of the case in the chamber is stopped by the belt which is really "headspace" but I assume you are talking about .020" gap at the shoulder from new to once fired. .020" is not that an unusual amount of shoulder gap for a belted case as I reload for several and they vary from .015" to .040". There is nothing that you can do to keep the brass from expanding that much upon firing. Creating a false shoulder or seating bullet to lands with a firm crimp will not work as it would on an unbelted case. Hornady used to make a hydraulic die special order but I don't think they do anymore. Like with any belted case there will be more thinning at the pressure ring with initial firing and it is important to push the shoulder back minimally after full expansion is reached (neck sizing only till crush fit develops) [/QUOTE]
