The CH dies I ordered for a 475 #2 Jeffery .488, came for a 475#2 .418. this after a long conversation with the owner about what I wanted. The shell holder for the 500 3 inch was so out of specs that I could not properly insert primers on any press or tool.

For me its Redding, Hornady or RCBS.

BobC has a set of custom dies for his 450/400 3 inch from Hornady that he is very happy with. Sent them two fired cases from each barrel.
