[QUOTE="J E Custom, post: 1960326, member: 2736"] If the inside of the neck is very clean or powder fouled and the sizing mandrel doesn't have anything on it YES. carbide is very dense and highly polished so it has the highest amount of surface contact and can apply more force than the shoulder can stand in some cases. different cases are effected by the size of the shoulder. (I used to shoot handgun silhouette and used a 7 TCU, A 223 case necked up to 7 mm) and it had very little shoulder And I learned to lube the expander ball to prevent crushing the shoulder. The sizing mandrel is a good place to occasionally use the sizing wax. It will aid the sizing and prevent crushing the shoulders from to much force. A little bit will go a long way. Be sure to clean the cases before loading. J E CUSTOM [/QUOTE]
