This sort of stuff really gets me excited. Now that barrels are almost hashed out thanks to the wonders of ECM milling technology, it becomes significantly harder to limit the global proliferation of firearms by people DIYing them on their own. Basically, this guy along with another guy I know called Jeff have been successful not only in rifling a steel barrel, but also drilling it completely. The ECM process doesn't care about hardness or whatever, only conductivity as far as milling goes so even 4150 steel is no problemo. Sure there's still limitations regarding making nitrocellu

I'd link the original DTIC here but the link seems to have gone kaput unfortunately, so I upload the powerpoint to here. Basically a short little overview over some R&D on projectiles designed with a Busemann's Biplane shape. https://en.wikipedia.org/wiki/Busemann's_Biplane https://apps.dtic.mil/dtic/tr/fulltext/u2/491944.pdf "retardation of tubular projectiles made from the 20mm american ball" https://apps.dtic.mil/dtic/tr/fulltext/u2/b087370.pdf "30mm

I've got some material you guys might be interested in from a guy called Jeff. Partially 3d printed revolving pump action shotgun he's done some work on. While it looks good here it still needs a bit more work from him. He's also done some really interesting work with home ECM drilling. I've got a link to an album of his short videos and pictures of his progress. https://photos.google.com/share/AF1QipPL_BjMquujSsvZ7GI4agkzNRans8eWeSYShzKFX5LzEi_dAU1oZk__nX-mUifCOA?key=ZkFVUWNKYW1XSGRMT2doMGdhYWRlXzVIQWM2Ty1n This doesn't include
