Cayugad, I also agree.

For Michigan, smokeless powder is not allowed in muzzleloading season nor is any type of firearmthat is not loaded from the muzzle unless it's a black powder pistol. Black powder or Black Powder Substitutes Only.
However, you can use smokeless powder in your ML if designed for it during our regular firearm season.

Looks like MS has elected to include the 45/70 to also incorporate folks shooting single shot stylesfrom the latter 1800's? And as an extra measure to help reduce and control the herd.

On the smokeless powder off topic during muzzleloading seasons,I'm notfor it but I'm not against someone that legally does either.

Almostall of the muzzleloaders that folks will carry in the field are not designed for smokeless powder use.

So anything regulation wise that allows for smokeless powder to be handloaded in the field in ML seasonswould be inviting more accidents in my view. Sure the regs could say "only if your rifle was designed for smokeless or even go as far as to recommend specific models", but I think the end result would be more folks making mistakes and using smokeless powders in ML's not designed for it.

Which will result in more folks getting killed or injured.

Plus, with smokeless powdersthat really opens up the door for extended lethal ranges far beyond black powder or BP substitutes capabilitieswhich from a safely perspective does not make sense to me.
