A complete and random stab in the dark

[Coop]

Reading another thread about gas blowback rifles and CO2 cargridges, I was thinking: Wouldn't it be possible to make a pump (or semi auto) shotgun with a CO2 12g cartridge and bb's built into a disposable (perhaps a spent real steel shell) shotgun shell like structure, that would work like the real deal, shooting would blast the 12g and bb's out the front, pumping the shotgun would eject the spent shell (the spent 12g cartridge, and carrying system for bb's) and load the next round.

 

It sounds like it would be a little complex, but I think it would add the ultimate realism to an Airsoft Shotgun. and with the power of a 12g cartridge, you can have some 20bb's fly out the barrel with a huge blast of frozen air, and with a large enough spread to simulate a shotgun, all while staying under the 1j limit (but getting really close, due to the power of compressed air)

 

Ideas...suggestions....anybody willing to try this out?

[bullzebub]

the 12g canisters is longer than ordinary shotgun shells ... but the idea is good ...

sadly it wouldnt be cheap...

[Sledge]

Yeah, you'd be looking at 50p-£1 a shot. That aside, I guess the idea is do-able. Maybe it would be better in a 40mm grenades launcher shell?

It's a good idea, but could get pricey. Of course if these models took off, the cost of CO2 capsules would plummet, and it would become a lot more affordable.

 

As the CO2 cartridge holds FAR more power than would be needed for a single shot, the remaining energy could be used to power a blowback mechanism too. That way, you could have Airsoft semi-auto shotguns with self-ejecting cases.

 

And herein lies the problem. As you would need one capsule per shot, and you would want the capsule loaded at the same time as the BB(s), the only way to do it would be to create some kind of case that would hold the capsule and projectiles together. This of course is now illegal in the UK (self contained cartridge systems). You could have 2 magazines - one for the BBs and one for the capsules, but this would seriously spoil the replica, as real shotguns don't work that way.

 

If you can find a way round this though, it would be a LOT of fun to shoot

[Longhairedhippy]

simple solution: have a box mag to feed the shotgun. capsules go in the rear section of the mag, BBs in front. both are stored separately, but loaded at the same time.

[Hairy]

Even more simple - load the BB into the shell, and keep the gas reservoir in the gun itself.

 

Just like the Digicon Target.. except that you have to pull the metal "cartridges" out yourself.

[Catchv22]

Or, get an M870 and get a CO2 rig, which is basically Hairy's idea except with multiple bbs.

[aimpoint]

this sounds like a really cool idea,would be fun to shoot aswell, super shotgun here we come

*EDIT*

o dear its only a mater of time before someone brings up the oicw 20mm cannon

[Longhairedhippy]

too late. you just did.

 

now that it has been brought up, wouldn't it be fairly simple to make some inexpensive (plastic, if need be) 20mm moscart shells that used the proposed small CO2 cart?

[Hissing_Sid]

Wouldn't the easiest thing be to get a cardboard tube, fill it with BBs and then seal it with tissue paper?

 

That'd give you a cheap, disposable, cartridge which you wouldn't mind ejecting.

 

I figure something like the centre out of a cash-register roll would be about right.

But does one really want a bunch of those lieing around their field?

If they're ok with 20,000 plastic BBs, I doubt they'll worry about a couple of dozen paper or cardboard rolls. What do you think?

[Megalomaniac]

paper degrades, plasic has to be worn down and the dust blown away by wind.

i don't think it would be possible to use CO2 capsule from all the residue it leaves behind in the barrel/insides, because i use this 12g CO2 capsule powered bicycle pump and it leaves white residue all over the inside.

That's ice.
