Belted mag brass after 2-3 firings sizing issues?

I bought the Willis collet for my stw and it works as advertised. I now use a Redding competition body die and shell holder set to size down to the belt and bump the shoulder in one op.

The Willis die is the way to go. It will resize about 20 different calibers. I found that Imperial Sizing Wax made removing the collet much easier.
