Double Column .22lr Magazine development? (Wonder .22lr)

[cleetus03]

From what I've read on the "internet" as well as here is that the .22lr can only feed reliably from a single stack magazine. If the magazine holds more than 10 rds it must also curve outward to ensure proper feeding.

With that said are there any ongoing developments in the firearm industry tasked to creating a double action .22lr magazine for a pistol or rifle?

Why do I ask you might say?........... Because I think it would be awesome to one day have "Wonder .22's" on the market. By that I mean 20+ rds of .22lr in a double-column mag the same length as a 10rd single stack .22lr mag.

Am I alone in thinking a reliable innovation like that would be a firearm breakthrough in all regard?

 

[MountainBear]

The difficulty lies in it being a rimmed cartridge. Most rimmed cartridges feed better from a single stack magazine. Not to say it couldn't be done, but I haven't heard anything being done. I'm not sure there's enough demand that isn't already met by the current offerings...

 

[gbran]

Don't know your answer, but I agree a hicap 22lr pistol would be great. I have a Magnum Research SA pistol with a 15 round mag.

 

[Fremmer]

Somebody needs to weld up a snail-shaped single column mag. And don't forget my monthly royalties.

not exactly a double stack, but i might refer you to the Calico pistol and rifle...which was available in .22lr and 9mm

they had 2 mag sizes...50 and 100

 

[cleetus03]

^ no

 

[chevyforlife21]

the ruger rotary isnt exactly single stack,

 

[Claude Clay]

according to Jean-Luc it was available briefly just prior to the phaser phasing it out but for historical value.

i know how the mag would 'look.' and it would be expensive to make cause of the close tolerances.
and slow to load. more an answer to a problem that really isn't.

I've got a double stack, 50 round Ramline magazine for my 10/22. It was a jam-o-matic for the first couple hundred rounds but since then I've put at least a thousand rounds through it without a single jam. Even with a rapid-fire full mag dump it doesn't jam now. I think it needed some wax buildup to smooth out it's inner workings. I can't seem to find a pic on the web to post. The one I have is clear and the design is really cool. It uses dual clock springs on the follower so it has constant tension from the first round to the last. It's a little disconcerting that, when fully loaded, somewhere in the middle there is always a gap between two rounds in one stack or the other. It looks like a jam about to happen but it always works? Hopefully someone will find a pic to post. If not I'll shoot some pics of mine tonight after work.

Found one on Gunbroker with a decent pic: http://www.gunbroker.com/Auction/ViewItem.asp?Item=144699117

I was going to suggest the Calico but I was beat too it. Fun gun dont know that I would ever buy one.

I have one of the original Ciener conversion kits for the M1911 and it has a 15 round magazine. Those went away with the "assault weapons ban" and I don't know if they've come back.

 

[Rembrandt]

Ciener makes high capacity .22 magazines for their conversion kits....but they are not a true double stack as seen below. Problem arises with the cartridges rim. Several unique designs have evolved that showed promise, the rotary has the best chance of success....to date Browning, Ruger, and Mitchell have all offered it.

 

[Vern Humphrey]

Not a double stack, but when you're shooting it, you keep wondering, "When is this thing going to run dry?"

 

[Claude Clay]

Rembrandt-- great pictures...of course
true dbl would necessitate slots for the rims; one side to the rear and the other a taste forward so
as you loaded one round back & the next forward to avoid rim lock. wider in the back tapering to the bullet and curved.

Vern-- my M-16 conversion is 30 rounds; long, thin & curved...cha cha cha

Mr.510--that the Ramline works means my daughter can shoot faster...sigh

 

[Rollis R. Karvellis]

On the new Colt AR 22's the rounds are off set for the rim, as far as fifty rounds go it would be alfal long.

Also of note is the American-180, which had up to 275 rounds in a pan magazine

 

[cleetus03]

Rembrandt, Thanks for the pics! I'm now in the process of trying to distinguish a rotary vs double-column feeding design.....

 

[9mmepiphany]

those were really cool. there was a demo of one at a nearby range and with the laser sight attached, it was blasting through cinder blocks and steel plate.

 

[hammerklavier]

With the right engineering a doublestack would be easy, basically you'd have two channels inside the magazine, perhaps with separate springs. When one channel runs empty, its follower would trigger a release for the second channel. It's the cost of R&D and production of such mags verses the relatively low demand that prevents its development.

 

[InkEd]

I have never seen one of those before now. It resembles a Thompson in appearance except for the top mounted magazine. Pretty cool.

 

[9mmepiphany]

i always thought of it as a bastard child between a Thompson and a Lewis gun...it's funny that they are both artifacts of WW I

Richard Lage has developed a double stack for use with his Max-11/22 upper for the M11/9. It can be done Look under "Project Status" and scroll down for pics.

 

[Mandolin]

The American 180 is cool...at 1200rpm and a 275 round mag, that's about 14 seconds of uninterupted fire. I just don't want to be the person who has to reload the magazine. Oh, and according the world.guns.ru, the company offers quad mounts for use in prisons. Now THAT is firepower.
