Yup, LEE will replace that shellholder. You'll be out a buck to send it back.
I believe you are right!!RC: I believe that you are focused on the primer too much.
OP is having issues with 9mm cases. While the "Bulge Buster" kits use FCD to push-through resize the bulged "straight walled" semi-auto cases, it won't work with tapered 9mm cases and you'll note the "Bulge Buster" kit is not available for 9mm - http://leeprecision.com/case-conditioning-tools/lee-bulge-buster-kit/wardor said:Are you using a "bulge buster" it looks like the ring from the push rod.
NOTE: 9mm cases are not able to be used in the Bulge Buster because it has a slightly tapered case
