Thread: ELD-M Getting Crushed when Seating

I have seen a ring around the top of vld projectiles when using my wilson seaters on brass with excessive neck tension but never dints like that. Are you having to really lean on the arbor press to get them to seat? did you chamfer the cases with a vld chamfering tool, are you lubing the case necks with graphite? Do you have a neck turning expander mandrel? if so I would run it through a few cases and try them. Is the brass brand new out of the bag or did you full length resize it for some reason first?
