In NC we have 4 muzzleloading seasons, in the 4 separate regions. The seasons are:

Eastern:
Muzzleloader 6-12 Oct
Gun 13 Oct - 1 Jan

Central:
Muzzleloader 3-9 Nov
Gun 10 Nov - 1 Jan

Western:
Muzzleloader 8-13 Oct
Gun 19 Nov - 8 Dec

Northwestern:
Muzzleloader 10-16 Nov
Gun 17 Nov - 15 Dec

The reason I added the Gun season dates, is that we can use muzzleloaders during the regualr gun seasons as well. The season bag limit, from opening of bow season thru the last day of the gun season is 6 deer. The central, western, and northwestern regions have a 2 buck/4 doe limit, but the eastern has a 4 buck/2 doe limit or all 6 can be does. Also NC hunters can purchase additional Bouns Antlerless Harvest Cards, which allow the hunter to take 2 additional does per card, and the hunter can purchase unlimited cards.
