The Calico uses a helical magazine, as does the Russian Bizon

There was also a spiral tub magazine in early Remington pump-action rifles that caused the bullet tip to line up with the rim of the previous catridge, rather than against the primer of the next round, thus allowing for the use of spitzer type bullets in tube mags.

Hope that helps.

Thanks!
I was thinking of a tubular magazine with the ammuntion in a line, like a Marlin 60 or Winchester 94, but where the tube is in a spiral or round configuration, instead of straight.
California's magazine manufacture/sale size limit has an exemption for "a rimfire tube ammunition feeding device." I wonder if I could design something that conformed with the letter of the law...

OK. Now that that's clarified, I'll see if I can find anything. I'm pretty sure I've seen one before (what Guntech posted may have been it).

Yes, there was a Remington centerfire rifle (a pump, IIRC) that used a spiral tubular magazine.
Someone will come along with the model number, which escapes me, I am sure.

Here's a cutaway pic of the calico magazine from Max's site:
The calico .22 held 100 rounds. Imagine if you could have a design like that with the barrel going through the center that would comply with the law. That would get DiFi's skorts in a knot!

Evens Lever Action Rifle
Everything old is new again.
Produced from 1873 to 1879, the Evans looks quite unlike most all other leverguns.
Made in .44 Evans Centerfire caliber, the rifle was a unique one in other ways besides appearance. It was loaded through the butt, where the helical magazine held 28 to 34 rounds, depending on the model. It holds the distinction of being the highest capacity levergun ever produced.

Well, here's the problem as I see it. I don't know of any modern rimfire tube fed rifle that did not require a plunger tube to provide force to push the rounds rearward into the receiver when the action is worked. Snaking a plunger into and out of the helical tube mag probably would require some work taking much longer than shoving a straight plunger into a straight tube. In a straight tube that has a lot of clearance between the rounds and the tube, there is very little drag and friction between the two. With a spiral mag, the rounds would see more drag and friction against the walls of the tube.
But, this is all IMO. Could be wrong and it wouldn't be the first time for me.

You could do it the way the Calicos do it, by having the inner "half" of the tube actually be part of the follower, that forces the rounds towards the feedlips as it turns, OR by having a slot along the inner part of the tube that allows a follower to stick through from the inside.
