all powder can be shot with the hot coat ... caswell got alot better price and i got a hotcoat... i shot powder i bought on ebay with it ,, and i am about to place an order with caswell for powder ... what is nice about caswell you can call them during hours and get tech support .. other companys just sell you the item and from there you are on your own ... i have been happy with every thing i got from caswell and they are a phone call or an email away .....
