What if you're backpacking into the wilderness and want to hunt deer with your bow and bears with a rifle? Couldn't you carry both while on the trail hiking in to your camp site? You're not actually hunting at that point, simply transporting the rifle just as you would in a vehicle. If you happen to see a bear while hiking in, set the bow on the ground, now you're hunting bear. Or, you see a deer, lean the rifle against a tree and pursue the deer. You're now deer hunting and no longer in possession of a rifle.
However, every officer and every judge is going to see each situation differently, based on several factors.
The WAC is a "rule", written by someone in DFW, without a law(other than time/place/and manner) to back it up. The issue would be proving a person was "hunting" deer with a rifle during the archery only season. Transporting a rifle (with a valid bear tag) is not per se illegal. For clarity sake, one might keep the rifle unloaded and shells in a backpack until actually hunting bear. Or carry a large caliber handgun and use it for bear as well as personal protection.
