[QUOTE="oldfortyfiveauto, post: 1211423, member: 30352"] Another issue caused by the expander ball I've not seen discussed is what the expander ball does to the case shoulder when it is withdrawn. The larger expander balls will actually pull the shoulder out as it is withdrawn effectively making the case longer (changes headspace). For that reason I often use an expander mandrel to control neck tension. [/QUOTE]
