DIY 20mm Cannon with remote Electronic Trigger
Josh writes …
I recently completed a home-made 20x102mm (20mm “vulcan”) destructive device, registered on an ATF Form 1. This gun is a single-shot, breech-loading firearm that lobs out a ~1520 grain inert steel projectile at an estimated 3100 feet per second. It’s locking mechanism can be nest described as being a very crude “falling block action”. The gun sits atop an M2 tripod from my 1919A4 rifle, and can be “steered” with the traverse/elevation mechanism. The cartridges use electric ignition, which I used a Nintendo 64 controller to build the remote control inside. It delivers a brief, but very intense burst of 300V DC to the primer, through an insulated electrode in the breech block.
Very nifty!
I founded TFB in 2007 and over 10 years worked tirelessly, with the help of my team, to build it up into the largest gun blog online. I retired as Editor in Chief in 2017. During my decade at TFB I was fortunate to work with the most amazing talented writers and genuinely good people!

What happens to the shell casing at the 10 o'clock to 2 o'clock position right in front of the "block"? Looks like that area is "open" and would allow for major deformation if not bursting of the shell casing.
Nice "Swivel Wolf"! I'd prefer a Birkigt 404 in 24.1x110mmR instead...
