Trying to remove the decapping pin on RCBS 7.5X55 full length die. Want to resize some berdan brass but can't unscrew the pin holder. The die is brand new. Hesitant to put too much pressure on it. Don't want to damage it. Tried pliers but don't want to put too much pressure on it. Think it would get ruined if I put it in a vise, use vise grips, a drop of penetrating oil? Any sugestions?
