I've just expanded and sized a bunch of 7mmBR cases with a CH4D die/expander and it works quite well. I haven't lost any yet but I expect to. I'm going from 7mm to .338 in one swipe.
I finally got a barrel blank ordered. Now I just need to decide whether to use the Mk X Mauser action or maybe just finding a CZ or Rem 700 action.
