A muzzleloader is really no different than any other rifle when it comes to bedding. Unless the barreled action is held consistently, accuracy will suffer. I bed all of my guns usually before firing the first shot. Getting a good stress free bedding job done is mandatory. I prefer pillar bedding with metal on metal as it will not change with the weather. Glass bedding is better than no bedding but still is not optimal. I bedded my Knights, TC Omega, Savage, and my Remington's. I also have bedded my TC Encore and Handi Rifle ML guns.
