[QUOTE="bigedp51, post: 1347661, member: 28965"] Increased seating force can also happen if you wet tumble with SS media or remove the carbon from inside the case neck. Add this to insufficient/improper inside neck chamfer/deburring and the seating force will increase. After wet tumbling I trim the cases and chamfer and before sizing dip the case necks in powdered graphite. Graphite is nothing more than very fine carbon and the expander will recoat the inside of the case neck..

Both cases have peened case mouths and need trimmed and chamfered. [IMG]https://i.imgur.com/CIxnlIW.jpg[/IMG] Many reloaders when loading bulk .223/5.56 cases on a progressive press use a Lyman type expander. They bump the case mouth onto the .226 diameter part of the expander to ease seating and reduce neck runout during seating.
