You are allowed on buck per year,regardless of which season it was taken. The early muzzle loader season is for doe only so you will need an antlerless license to participate in it. The late flintlock season allows you to use your buck tag for a buck or doe if you have not killed a buck, if you have killed a buck you will need a doe license to take a doe in that season bt you will need a flintlock gun to hunt that season.
