In the top B & C whitetail states as recently listed in the American Hunter, smokeless muzzleloading is legal in all of them in muzzleloader seasons. Regs change from year to year; as the VA DGIF themselves are recommending smokeless be made clearly legal in muzzleloading for deer and bear, the rest is just a formality.
A few western states, like Oregon and Washington State, do not allow 209 primers, and you need an "exposed" ignition system-- so not only is smokeless a ways off, you can't use an Omega, Encore, etc., to muzzleload with or a Savage.
