Do they control the type of fuel that can be used in racecars? Not a race fan, so I don't know, but I doubt they would let stock car users use rocket fuel even if they could somehowsafely use it in their car.

Black powder substitutes pretty much equal the power of black powder volume for volume. True smokeless powder is "jet fuel" compared to them, which is why they don't allow it.

You want the power and trajectory from your blackpowder that you get with your 30-06, and that is fine, but I will lobby to keep the use of smokeless in rifle seasons. For "special" blackpowder seasons we don't need it. And I am pretty sure that smokeless muzzleleaders are legal in any "rifle" season.
