Is it possible to manufacture a clear shellcase for the purpose of a slowmotion capture of the ignition? Maybe you’ve seen some video’s like the slowmo guys on youtube.
I’ve looked and found that pressures can reach 45k psi or 3k bar, but I’m not sure if that is only for the barrel. I would imagine the pressure inside the shell to be equal if not higher.
Or what about the barrel? Can you make a see through barrel of high performance plastic/polymer? Maybe with reduced projectile charge? Just a 1 time fire? Still be a nice vid to see a clear barrel get shattered by a fired projectile.
