Traditions Deluxe Powder Flask Brass With 30 gr. Interchangable Spout and Valve. This is a New flask for carrying Black Powder and Charging your muzzleloader. Handy to use in the field or range. Easy to fill by removing the threaded bottom. Will set on flat surfaces or is handy to carry in a pouch or pocket. A heavy walled brass flask that holds approximately 2 ounces of black powder or Pyrodex equivalent to 875 grains of charges. Many spouts will interchange. Thanks Danny
