matching volume-for-volume

@propyne you know, if I can get the people together, maybe it can be a reality

@propyne just need to call up Lehigh and beg permission to machine something like that

Why would you do such a thing

Beautiful.

Can it actually feed from that magazine?

I... dont know what its supposed to be...

Like either the "pump" or the magazine "feed" is funtional

I guess thats what its depending on

An AK-00? Or is a 12 Gauge-47?

Still... its base is definately a shotgun..

But I dont think the pump is gonna move far back enough to "feed" the shells into the barrel

i don't understand why no one has developed a rimless shotgun shell

it'd solve all the problems with feeding from magazines.

I'm guessing the issue is getting enough charge out of the primer to set it all off properly. I'm not aware of any rim fire cartridges with charges approaching a shotgun shell.

i don't mean rimfire, i mean a rimmed case

Interesting.

i'm certain that with modern materials a rimless shell could be constructed. you'd give up the ability to have different lengths, but that wouldn't be particularly important in a self-loader meant for rapid fire close range fire.

@Atkins you could just make a sleeve which evens the rim out

sleeve wouldn't even need to be the full length of the shell

maybe make it 1/3" wide, and place it 2/3" from the base

i don't think that would be adequate to prevent rimlock

why not?

I guess you could make the sleeve full length then, with a taper down to the rim.

ideally you'd have something as close to a perfect cylinder as possible to prevent any tipping or rocking

(which is what prevents rimlock on fully "rimless" cartridges)

which, incidentally, have rims, lol. (whether you call it a "groove" or a "rim", it's the same geometry)

@Atkins you want to go into business selling pieces of slightly tapered plastic tube which convert standard shotgun shells to "rimless" (a.k.a. groovy) shells?

we can file the patent on Monday

Standard license fee for the advanced alien technology: 0.02USD (or about 3-6% of the cost of a standard 12ga shotgun shell)

*i prefer my slingshot from walmart*

woo

I got a shield 9x19

Best groups were around 1" at 7

but it took a SHITLOAD of practice because I have giant hands
