Fireball, I started with the wsm cases when I ended up with the EBG. The problem I ran into was case wall thickness variance. ( section a couple) The brass was as thin as .008 in the shoulder of a few cases . I also tried RUM cases and gave up there too.
That being said Dave @PTG has a print for a 500 rem ultra...so somebody has tried it. Its sheet #3576 if you want to get a copy from Kathleen or Myra.
