Photocopier 80 gsm paper case, 7 layers taped, no glue. 5 mm ID, 60 mm length. 2 mm diameter cavity, depth 20 mm. 40 mm grain length. Cat litter nozzle 5 mm thick. Bulkhead of paper wadding, end crimped over, no hot melt glue.
Standard meal blackpowder propellant.
Conventional bamboo kebab stick for a stabiliser. It was painted red to aid recovery, and labelled as usual with the ID code for this shoot batch (#2).
Masses were:
Case: 1.16 g
+Nozzle: 1.31 g
+Propellant: 2.97 g
+Stick: 3.78 g
+Fuse: 3.86 g
First fused with loose meal prime and a meal-IO paper fuse. It did not ignite. Was later refused after cleaning out the cavity with a new meal-NC tissue paper fuse.
Spectacular CATO!
Case totally shredded for 25-30 mm down one side, stick detached, bulkhead wadding blown out. Bits and pieces scattered for several metres. Nozzle was not recovered.
I believe the case was simply too flimsy to contain the normal operating pressures. Although I may have damaged the grain while refusing after the initial fuse failure.
