I'm only going to be using .22 shorts for grouse in my backpacker. I bought the .357 one just because I was paying shipping anyway. I'll shoot a few cast .38 plinkers out of it.
Now I have a backpacker that shoots 12 gauge slug with a .410 and .22 adapter for grouse.

Let us know how it works. I would even consider permanently attaching a .357 adapter to a backpacker to have a folding 38 special carbine if it could hit a tin can at 25 yards reliably.

38 Special fails to penetrate cardboard at 100 yards, who knew?
Edit: The longer rifled inserts, I'm just thinking they would spin in the barrel in the opposite direction to the bullet. Which doesn't sound great for accuracy, maybe you would have to JB Weld the thing in. On an old single shot with a bulged barrel that wasn't fit for much else, say. You would need adjustable rifle sights though.

Well .38 special HBW's loaded backwards will penetrate one side of a 45gal steel drum at 100 yards and leave a welt on the other side expanding to .70+ caliber............Harold
 
I must say that the 3" non rifled adapters I have are not that accurate. I have tried a 12ga to .410 and a 12ga to .22LR. 30-50 feet accuracy for the ones I used. Still, I'd love to try a 7.62x39 adapter out of the singe shot 12 gauge. Rifled would be better, but they are more money and not as handy to thow into a pocket or ammo pouch.

The longer rifled units typically have rubber o-rings on them to help hold them in place in the barrel so that they don't move around.
 
I haven't got to the range yet with the Dina arms .22 and .357 inserts but I did test fire it just now when I was walking the dog.
I'm very impressed with how quiet the .22 is with shorts. Perfect for grouse when elk hunting. The empty .22 shells fall right out, .357 is held in with a rubber O ring. The only malfunction was missfires from some old .22 shorts.
I forgot to mention, I have a couple of .410 inserts from another site sponsor. I find them very useful.
 
12GA actions and especially aluminum 12GA actions (Turkish shotguns) are not rated for the pressures of any rifle rounds, not even 7.62x39 and 223.

Pistol calibres are possible but with the cost of quality steel, machining chambers and actually rifling them, we would be no cheaper than any other vendor.

We may look into 20GA and .410 adapters.
