if htere are machine guns and submachine guns, shouldnt there be supermachine guns??

>shouldnt there be supermachine guns?
Those are autocannons and high rpm rotary guns.

Yeah, autocannons.

An anon the other day coined the category of “super sub machine guns”. These are guns like the m2 carbine chambered in high energy straight-walled cartridges.

>>64014313 (OP)
No, but there are dom-machine guns

>>64014326
>high energy
>straight walled cartridges

Pick one dummy.

INB4 Muh 45-70 shut the fuck up hopalong, the thread is about super machine guns

>straight-walled can’t be high energy

Are you retarded? High energy has to do with propellant volume, not caliber. Pick any cartridge you’d consider to be high energy and neck it up to where it’s straight walled. Voila, you’ve created a high energy straight wall cartridge. 50AE, any fuckhuge revolver magnum cartridge, 350/400 legend, 577 tyrannosaur (or whatever it’s called), etc.

You’re still stuck on small arms, we’re talking about autocannon ammunition. Like the Bofors 40mm round.

Straight walled like a rimmed revolver cartridge; cylindrical? Or straight walled like not a bottleneck cartridge?

>>64015141
AFAIK modern tank cases are straight-walled but they're also semi-combustible so they only have to eject the base.

>>64014313 (OP)
>super
It's SUPRA. It's a whole nother level

>>64015190
Not bottlenecked. A slight case taper to aid in extraction is still considered straight walled.

Would it be possible to scale up the M60 to shoot the old 8-inch brass cased shells the USN used to used?

>>64014313 (OP)
why does the top one have dicks cut into the forward grip

>>64015876
That is a very homosexual system for mounting accessories, called KeyMod. That must be why it failed against m-lok.

reminder that the existence of Submachineguns implies the existence of Dommachineguns.

The older I get the less compelled I am to call guns anything other than a "gun". It's not a smg, lmg, carbean, dmr, xmr, whatever. it's a 'gun'.

>>64016847
In days past, guns and especially calibres were sufficiently limited to neatly fit them into categories. Now it's intermediates upon intermediates, to the point where "gun" becomes a continuum of technical possibilities.

>>64016847
after seeing all the different cartridges, the legal names, the historical names, technical names, it all starts to just blur
these days most people don't even know what an autorifle is

>>64016847
Move dots forward reeeeeee

>>64016847
I just call them rifles. This is a gun.

>>64017086
I respect that naming convention.

>>64014313 (OP)
they call those "autocannons"

>>64014313 (OP)
>>64014326
On this note, I've thought for ages that we need a proper term for "SMG-style" semiautos. PCC doesn't really work since it doesn't include "pistols" and does include guns like the Ruger PC, Henry Homesteader, etc. that aren't SMG-like.

BOFORS'EEZ NUTS

Poost it up your pooper hole

What about a Ultramachine gun i.e Ultralightmachinegun? In that case you are looking for the LAD.
