Reloadable Artillery Shells are the consumer equivalent of what professionals use in large public shows. Each kit comes with a number of shells (6-24) usually, and a number of launch tubes (1-12).  These give you the largest breaks allowed by law with most shells having 60 grams in each shell. With the wide variety of effects found in shells, and the fact that most of these fit our consumer Mortar Racks, you can do a show just as good as the pros.
