To begin with,take breechplug out and remove the whole mess from breech end,then PLEASE go to an experienced muzzleloader guy and have him show you-in fact-just let him remove it,then buy the correct bullets/sabots/powder/primers and load EXACTLY the way they teach you. Don't wait very long to do it either as unburned powder still attracts moisture and will rust your gun if left loaded for a long time.
