Idaho, Oregon, Colorado to one degree or another. Idaho is pretty much "traditional" and nothing else. No inlines, no sabots, no enclosed ignition, no 209 primers, lead projectiles only, no scopes, etc. Colorado is kinda "in between". Not familiar with "every" state, but there may be others. I think Pennsylvania has a "primitive" weapons only season, as well. Louisiana has a primitive weapons season, but it is a joke as it allows break open single shot centerfire cartridge rifles to be used. I guess in Louisiana a single shot centerfire is considered "primitive". Go figure!
