A smokeless muzzleloader is the biggest abortion i've ever seen.
It uses smokeless powder, a modern smokeless bullet, and a smokeless primer. All that's missing is the brass case. Which is replaced by the barrel. Then it's scoped like a smokeless scope. It even uses the trigger from a smokeless gun.
It belongs in the rifle season with all the rest of the smokeless guns. Which is the only place it's legal in Colorado. The states that allow it in ML season have their head up their azz.
My unbiased opinion.
