Description
Please Note – Most Propellant Powders are in Stock but this can change daily due to exceptional demand at present.
We can no longer courier / post / send shooter’s propellents due to TNT withdrawing that option so these products are collect only.
We have to restrict online purchase and only sell face to face on production of a valid FAC, thank you for your understanding.
Please note we cannot post this item. Delivery or Collection should be arranged prior to purchase.
