Long/short..after changing calibers for the first time on my Dillon Square Deal B, about 10% of the rounds were ruined (RUINED!!) because the bullets were canted at station 3, where the bullet is seated but not crimped, causing the bullet to SQUASH the case...I finally realized I had left out the part that goes into the SDB body at station 3, looks like a funnel, causes the bullet to straighten as it goes into the case...oh, well, another day reloading, another 20 .357 mag cases and bullets ruined. RUINED, I say...FM12
