You can Google up the shellholder number. My reloading gear is in the barn workshop, so I can't go look at it to get the number. Anyway, there were always some cases that were snug in my 220 shellholder, though I don't remember any that wouldn't fit at all. The 220 cases and that shellholder were the only combo that has ever given me any fit problems.
Still, Norma brass is my favorite for all of my rifles.
