Michigan's deer season gets under way this Friday, Nov. 15th. gun) Michigan in 2012 had approximately 660,000 deer hunters and the use of a muzzleloader as a primary firearm is growing. I placed a poll in one of the deer hunting forums, asking what weapon hunters would hit the woods and fields with this year in our REGULAR FIREARMS SEASON. With close to 350 respondents today, 24% of the hunters will be using the muzzleloader as their primary firearm for opening day. That my fellow shooters is a substancal amount. These hunters could have used a handgun, centerfire, shotgun or a bow. How's the other states faring?
