20mm project

[TN_boy]

Working on an underwater gun at work. Supercavitating projectile. Initial testing we were able to penetrate 1/4" steel plate @ 30ft standoff underwater. Hitting target within 1" of aim point. Currently working out velocity on new gun design with air shots reaching velocities around 3250 fps with our 72" barrel and 2700 fps with our 30" bbl.I

t's stinkin loud!

Velocity measured with break screens connected oscilloscope and verified with high speed camera (30k frames per sec) and fiducials.
