Welcome to the Indiana Sportsman - good to have you with us.
Here are the 2005 dates for deer
Firearm season- Nov. 12, 2005- Nov.27,2005 (muzzleloaders can be used)
Muzzleloader season- Dec. 3 - Dec. 18
You can use a muzzleloader rifle or shotgun to hunt about anything in Indiana during the season.
What part of the state do you live in? I don't know about all areas but I know Pigeon River State Fish and Game area isn't overly crowded during the muzzleloader season.
