There's a Group Buy Discussion Thread on the NOE Forum for a copy of the RCBS 45-325 FN/300gr HP going on now. There are around 10 people so far who would like to have one of these moulds. A few more people joining in would push this one to an Active Group Buy soon.
Here's a link to the Discussion thread: http://noebulletmolds.com/smf/index.php/topic,69.0.html
Please check it out!
