I live in WA and recently got my approval for a .404 Jeffery. It took a while and I did have to have an interview with the district superintendant of police, but it all came through good in the end. He said if I was a member of the big game club I would have no trouble at all getting approval for it.
I know someone waitng to get approval for two large calibre rifles at the moment, when and if these get approved I will post it here.
