I just dropped back over to the RCBS site, and realized that I'd mis-read the price list;
http://www.rcbs.com/equipment/list.html I was reading the price for a Shell Holder Ram, at 20.95... the shellholder itself is only $6.
Looks like I'll be storing the primer tool until I get a single-stage for doing a few rifle shells somewhere along the line.
