does this ammo even qualify as a "fixed cartridge" legally?
it has no case or primer, it's just a hollow bullet full of powder.
if not, this would technically be a muzzle loader and unregulated.
which i suppose it is since the bullet is fed from the front of the chamber, it is de-facto not breech loaded.

I still dream about the following:
>M82A2 style where the gun protrudes behind the shooter's back
>long recoil with even more travel than the GM6 Lynx, thanks to the extra space behind the shoulder
>shoots 20mm grenades like the ones for the Neopup, or 30mm ones like the new Barrett grenade launcher, or maybe something hotter if the forces math out
>primarily meant for a subcaliber saboted penetrator with stupid high velocity

>CT or caseless rounds feeding into the front of the chamber are technically muzzleloaders

And muzzleloader are exempt from the typical gun laws right? This is hilarious. Can you just make a CT full auto SBR and circumvent the NFA?

Unfortunately, no. Muzzleloaders are unregulated because they do not use a fixed cartridge, not because they're muzzleloaders.

To get around the law, you'd need a weapon that has no cartridge at all and separately loads powder and ball. Which is definitely possible, as there were some historical repeating flintlocks that had a magazine of balls and a separate reservoir of powder, with a mechanism to reload the chamber with the pull of a lever. Using modern smokeless powder and a gas system, something like that could be made to function as a quasi-legal machine gun.

What would be a good way of keeping the fouling down to a minimum? High quality powders is one, but would a different kind of metal for the barrel keep the carbon from sticking?

>>64500630
if it has no primer or case, is it still a cartridge?

Check this out: HK NBW, caseless handgun using technology from the G11. Has a translating rather than pivoting chamber, external propellant cartridges, and a concussion primer.

>>64502153
yeah basically same idea but better cartridge and chamber design.
didnt know about this pistol though, neat

>>64502190
I really like your design OP. I thought internal propellant caseless was better than external propellant caseless or polymer CT for handguns for a while, but I had different ideas for the action, including gas-operated locked blow-forward.
You might want to slightly modify your illustration to make the grip angled though. Your feeding mechanism lends itself well to straight magazines inserted diagonally. Push-through feeding eliminates the need for tapered cartridges too.

>>64502373
good point about the mag angle.
the cartridge isn't tapered in the image.
it doesn't eliminate the need so much as it makes tapered cartridges impossible.
tapers are actually good for packing more powder behind a smaller bullet.

>tapers are actually good for packing more powder behind a smaller bullet.
That's really an advantage of bottlenecking rather than case taper. P. O. Ackley reduced taper for more capacity after all.
I think this is the main point of comparison for internal vs. external propellant caseless. Internal propellant benefits from a larger diameter bullet, much like a straight wall handgun cartridge case, while external propellant caseless like the G11 benefits from having relatively small diameter bullets, which lacks an immediate analog in cased ammo but resembles bottlenecked rounds in usecase.

>>64502451
i was thinking of taper more in the sense that there is any diameter difference between the bullet and case but yeah no bottlenecking is really what i meant.
i think a hollow bullet with a heavy wall could be good, similar to the principle behind aluminum core 7.92 cetme.

This but with HK stamping

It's clearly not, but it will counts as one legally anyway. Daisy made a gun this way forever ago and the courts decided that it was legally a firearm because fuck your rights.

An SMG type platform that take 7.5fk. I dont get why Brno decided to make only a pistol that takes it

>>64500162
Wouldn't that be the 30mm Maadi Griffin? Pretty sure that's the one that shits the entire gun out the back every time it fires.

>>64502637
whats it called?

>>64502093
Yes. See the Daisy VL rifle and the Voere caseless rifles.

>>64502666
thats the HIWS

>>64502622
would this theoretically work with strong parts?

>>64502857
if you made the space to feed large enough to fit 5.56, yeah.

>>64502706
Daisy VL

>>64502791
That's not the gun I was thinking of, but that's also awesome. At that size though, I'm not sure why you wouldn't go with a Charlie G.

new and improved with actual muzzle loader projectile and pellet

>>64503794
The front of the chamber is not the muzzle.
