[QUOTE="woods, post: 980203, member: 6042"] Yes and this is why the belted cases are more prone to a case head separation. The primer fires, the case moves forward to contact at the belt then all the rest of the case has to stretch to reach the shoulder. The brass is moving forward right when there is a lot of heat at the pressure ring right in front of the belt and it thins the most But if you only set the shoulder back a minimal amount once the case has fully expanded forward and you get a crush fit, then you will not exacerbate the thinning at the pressure ring Keep the "shoulder gap" (for lack of a better term) minimized and "headspace on the shoulder" and a belted case is just like all the others [/QUOTE]
