I would have thought that was a SNL skit - a joke - but apparently it is not.

Why would you want a "revolver cylinder" that holds one each of many calibers? The cylinder appears to be the barrel too, otherwise it wouldn't work. What's the advantage of a "cylinder" that holds one each of .45auto, .40s&w, 9mm, .38special, .380auto, and .22lr? Plus, that "cylinder" is really big! Same things goes for their other "cylinders" that hold rifle cartridges (ignoring for the moment that a rifle cartridge fired from a six inch cylinder/barrel will be significantly neutered - oh, but what a glorious muzzle flash and recoil you'd have!)

I seriously doubt this "innovation" will find much demand. A much better investment would be ammunition for a pistol/revolver/rifle that was designed for a specific caliber. That way you won't need to Scavenge for ammo and have a single barrel out of multiple cylinders that's useful. Gimmick.

If I hear right, it "only" weighs 3 1/2 pounds....better putting that weight into something more useful - water,shelter, warm clothing.

I don't understand this "scavenge for ammo" idea. I hear people talk about it, but I don't understand it. Where do they expect to "scavenge" in a short-term survival situation? The shady spot under the ammo tree? The local gun store? Wal-Mart?

Well, it's kind of horrible sounding, but a good place to scavenge ammo is off of dead guy you just shot. But it's actually more useful to just take his gun right along with the ammo. That way you have a spare. And something you know will work with the ammo you just scavenged (one would hope at least - it's possible that the dead guy finds himself in that state because he had the wrong ammo for his gun!)

Better yet, don't be an idiot and plan on scavenging ammo in the first place. Have enough on hand to get the job done from your private stock.

p.s. - You should have your own "spare" guns too, so you don't have to depend on the dead guy supply route.

WalMart will be stripped of anything useful within 3.7 nanoseconds of the start of a disaster, no need to even try looking for ammo there...

What if the dead guy had one of those useless multi-caliber rifles? Probably what got him killed.

Murder and mayhem will then decline; it will be the dawning of the Age of Aquarius....

You should've been watching The Walking Dead. It's really educational, they scavenge for ammo all the time.

On other hand, it's easier to carry a 3 pound 23 calibers thingy and scavenged ammo than the same ammo and 23 (x 3 pounds) pieces of different caliber spare guns...

But I agree with haertig, having these calibers quite neutered anyway, it could be more practical to carry a 12 ga smooth bore with a set of multiple caliber ammo holder inserts (It seems to me, I saw such a solution already marketing).

Personally, I would rather rely on reloading my .357 cartridges with any scavenged ammo components. The minimalistic pocket lee loader is under a pound + 1 pound .358x158 mold + a pound of primers should go for a long time. I understand the risks of using unknown propellant, but it is possible to figure how to ration it safely based on the scavenged cartridge size or, if time permitting, test firing varied loads. Also I've read that my Rugger GP100 is tough enough to handle load errors.
