Colorado also doesn' t allow Pyrodex. And up until 2 years ago didn' t allow in-lines. Which brings up a question, what is the advantage of an in-line? BareBackJack says we ought not allow them. But do they really have that much better of a range? I mean the old Hawken rifle I had was probably capable of a kill over 100 yards but I wouldn' t have felt comfortable shooting it that far. (As if I could hit anything past 100 yards with open sights.)
My opinion is that you get more " better" hunters during the muzzle loader hunt. By that I mean it is guys that are capable of getting the sub 100 yard shots. Not these guys who sit on a rock and lob artillery at something 300 yards away.
