Rimless casws can be printed, but in a semi autonatic action, they like to shear at your deposition lines even when resin printing. Like I said, you can add metal reinforcement for added strength that prevents the shearing but its more work.
And drilling a chamber isn't hard either, especially if you're printing a telescoped cartridge. You can use an end mill to drill out your chamber,bthen using a taper cutter, you can cut an ever so slight taper in your chamber using a taper cutter.
Chamber size is uniform because your case is a tube basically. And the taper is to aid extraction, though you could make a tool to electrochemically cut flutes a la the G3 that would do a much better job.
As for the groove itself, all you need is a small endmill to drill out the notch necessary for your internal extractor. Man, the rest is just designing your bolt. Yeah, it takes a bit of hand fitting tomake the extractor, but I've made em out of steel without issue.
The point isn't to make a better mousetrap FGC9 in 9mm shooting blackpowder, the point is to make a FGC556.
Its like, the Lutty was a statement which was "you cannot effectively ban guns when out of sheet metal I can make a gun". The FGC9 is very much an evolution of that statement, and everythibg since then has been an expression of that. My research is the word of god saying "I double dare you". To that end, you get some mechanical complexity but dude, you're going through all this work to build a gun and procure ammunition. Why settle for an acient history SMG when a rifle and a completey unregulated across the country optic changes history?
Yeah, I have flexibility in my engineering being American, but theres a massive advantage to telescoped cases and the inherent additional complexity, in that you get P90 space magic from a telescoped case, along with some traded off ease of manufacturing.
