Just a quick note of praise for RCBS Customer Service. I had ordered a set of RCBS .45/70 dies (thru Midway) knowing that the stock seating plug was for a round nosed bullet. I figured I'd call RCBS and order a flat seating plug. When I called RCBS they simply asked what I needed, and then took my address and said , "it's on it's way at no charge - a full set of three seat plug profiles".
Crazy good customer service. That's the way to build brand loyalty!
