Many of you know that I work on Battleship Iowa in SoCal, and that we shoot some guns on occasion.
One of the guns we shoot is a USN 40mm Salute Gun like this one:
40mm cases are not easy to come by and we only have 1 good one (a second one is split). They are steel and cut to about 7-8" long and modified to take a .38spl blank as a primer. The charge is 1/4lb FFG or FFFG. The report is sporty.
What we are trying to do is machine a piece out of steel or brass, with an appropriate bore (~1-1.5") and an OAL around 5-6" and walls about .250 thick.
These loads are gently compressed and held in place with a cardboard wad.
Are we safe here with our dimensions and materials, or are we in a danger zone?
