I’m on my third reading. I find some new detail every time.
After I read about it, I had to look it up and found a guy in a local gun club who owned one. He told me if I could pay for the ammo, I could shoot it. He has empty 20mm shells, but finding the appropriate amount of materiel to craft a bullet is difficult.
The damn thing is VERY heavy, and the one he has had the sleds replaced with heavy-wheeled cart.
Could they be turned from copper or brass bar stock? It would be a hoot to shoot it!
