This last season I hunted with a smokeless inline MUZZLELOADER, albeit with open sights, because the MN DNR says that's what I can use during MUZZLELOADER SEASON. It's important to note that I did not hunt with a traditional gun because our state doesn't say it's a traditional season.
It's an old argument that will never go anywhere because people can't look beyond their own opinions. If you don't like the way your state defines a muzzleloader, get over it or move somewhere else. That's like me yelling at you because you were driving the speed limit in a blue car, even though I personally feel like you should have been driving slower in a red car. It's pretty childish.
I'll stop now.
