I need to find someone with a 300 RUM that reloads and uses RCBS Full Length dies and RCBS shellholder so that I can size a couple pieces of brass. I have Hornady Custom Grade dies but they don't size the brass down enough to work in my chamber. Fired brass rechambers easily but once I run the brass into the dies it doesn't want to chamber easily. I am trying to determine if buying a new set of dies will fix the problem. Can any one meet me somewhere? I have a press mounted for portability and could meet you to resize a couple of my brass. I am in Vancouver WA.
