I know it’s a crazy request but does anyone know where I can find a magazine or 2 for the universal 256 ferret? Thank you

That is quite a reach. Have not seen a 256 Ferret/44-magnum magazine for sale in….well, never. Too bad the 256 did not have a rebated rim. The 256 is a necked-down 357-magnum I think. There have been attempts to convert carbines to 357 using a pistol magazine. Use of a single-stack pistol magazine that would accept the 357-magnum round inserted into a 30-caliber magazine shell might be the only option, but any time one tries to feed a rimmed cartridge from a stacked magazine, feeding becomes very problematic. I have done that very thing with a 9mm conversion and it might be your only option. Good Luck!

Thank you very much for that option, you are correct in it being a necked down 357. I came across the rifle, of course without a magazine & have been looking everywhere but no luck at this point. Thought it would be a neat rifle to restore but without a magazine, it’s kinda useless. Thanks again!

You can usually find that seller at a gun show that shows-up with a box of magazines that nobody knows what they fit. I have shopped those boxes before and found some pretty interesting and useful jewels. Maybe the first step is to shop for a single-stack mag that will accept the round (even if only a few) and will fit inside a 30-caliber mag shell ….then go from there. A discarded or damaged shell can be found. From that point, it’s a matter of trial-n-error to fit the assembly in a fashion that will feed and secure the mag inside the shell. I have used washers as spacers then silver-soldered it all in place. That did actually work for me after a fashion until I partnered with a fellow forum member that came up with a better idea, but it did work.

there are some pictures of what they look like on the Ferret page" rel="nofollow -

some of the mags in the carbines pictured appear to be steel?

OAL of the Ferret would make it very difficult to find a pistol mag it would fit, but there could be something out there. Might be possible to make a steel 30 caliber work with some feed lip reforming and maybe replace/modify the follower to single-stack. Might do some playing with a 357 round, I have those. Followers can be built from a product like Delrin. My buddy 03man knows how to do that.

30-caliber magazine might be the best candidate. Have to stack the top round with the rim in front of the preceding round and maybe only hold three, but three is better than none. This pix shows two 357-mag rounds stacked in a 30-caliber magazine. I am thinking there is enough room to slide sections of sheet-metal into the inside on either side of the shell at the feed lips and reform some lips. A new single-feed flat follower is fairly easy to build. Of course, one would have to be able to braze or silver-solder things in place. One might have to tweak the opening in the front of the mag as well. The Sten Gun magazine actually has double feed-lips, so it's not a new concept. I suggest a single feed as that is what the original Ferret magazines are and they are much better feeders than the double stacked USGI.

If this were mine, I would be compelled to try this. Don't know why, ammo is about as scarce as chicken lips, but I am old and bored.

I definitely appreciate all the input & suggestions. After I track down some ammo, I’ll have to see if I can make a magazine that will work. Thank you again!

Who knows yet. You might be able to get 256 to feed out of a 30-caliber magazine. This has to be one of those labor-of-love projects. The 256 probably flies better at range and maybe more accurate, but a 7.62 x 33 loaded with a light projectile can easily duplicate the 256 performance and energy-wise, outperform it.

All else failing, you could convert it to 30-caliber with a barrel change, say a USGI used or import marked, which do occasionally show up at reasonable prices. I have found them for $75-$80 for shooters. The bolt might still work, but the extractor likely requires replacement. You would have no rear sight, but the receiver was tapped for a scope-mount. You could maybe get by with no more than a couple hundred dollars or less and wind up with a shooting 30-caliber carbine. Or sell it to me real cheap….😁.

I was surfing around and found a Marlin 62 256-magnum magazine for sale on ebay. Marlin chambered the 62 in 30-carbine as well as 256 and the seller states this mag is for 256 or 30-carbine. So, size-wize the shell might could be adapted to a 30-carbine trigger housing. Probably too much of a reach, just tossing it out there.

Took me awhile to remember this source for the .256 Win Mag/Vulcan .44 mag magazines..." rel="nofollow -

Not cheap and I can't guarantee the quality,

Thank you, someone else also sent me that link thinking they may work but weren’t sure. It’s funny because they show in stock, I ordered one to try & then was told it’s on back order so I’m not sure if I’ll get one or not. Thank you again

That seller has some ammo, brass and even a complete rifle posted as well. Don’t see these often. If you’re into it for real, better jump on the mags, brass and ammo.

Congratulations to Wodash for winning, At the $755 for two magazines I would hope they are going to be reversed engineered as evidently two people were interested in this price.

Start bid about $150. Would need to keep that one in the safe. Pretty sure I could build something that would work.
