Whidden "click" Dies

It's not perfect because as the brass work hardens from multiple firings the spring back is different than brass that has been fired less. For instance, I have one lot of cases that have been fired 12 times and another lot that have been fired only 3 times. These lots will not size to the same shoulder bump clearance that I'm looking for unless I add or subtract shims.

This is precisely why I anneal every loading for my competition loads. It negates the effects of hardening and variences in springback.

I’m a big fan of the Redding Competition shellholder s. They allow precise sizing, and you can use them with other cartridges with the same sized head. Gotta love a versatile tool! Lol
