The Black Widow mortar kit is the end all, beat all, mother of loudness when it comes to Artillery Shells / Mortars.
The Black Widow artillery / Mortar kit contains 24 massive reloadable 60 gram canisters with 24 different special effects. The shell easily goes over 150 feet into the air and breaks in big, loud, beautiful effects. For shell effects, I may have to give Excalibur shells the blue ribbon, but these aren’t far behind. If you want it to sound like you’re firing a cannon when it goes off and when it breaks, then these are the shells for you.
