Im looking to purchase a Black Powder Mortar. Curious to know how they perform. Im am thinking of getting one for New Years eve and just keep blasting it all night lol. I would like to get one that has a "deep boom" rather than sounding like a pistol going off. Right now, I dont have any plans to launch golf balls, tennis balls etc out of it. Any ideas on where I can get one that is reasonably priced? I see some of them online for around $400, but thats way out of my price range. I have seen some for around $100, but would like to know if they will perform like I want it too.
