Bearhunter,
It is leagal to hunt in a firearm restricted area during the rifle season if you use a bow or a muzzleloader with your rifle tag. Muzzleloaders are considered limited range weapons and are leagal in a firearm restricted areas. You may use legal shotguns fireing slugs or buckshot also see page 67 in the Wa. big game rules. The grey area and there are many in our pamphlet is also there on page 67 it says under 2) Muzzleloader tag holders are ristricted from hunting that part of GMU 652 outlined for King County but in the next 3) Modern Firearm it does not but lists the legal methods. so are we to assume the same is true under 3) that it states under 2)? I would still hunt that with a bow just to cover myself but if you were hunting it with a muzzleloader during the rifle season I think you would have a case with the warden.
