Can you shoot a 410 in your 12 ga?

I've been looking for a .22 adapter for a while that I can use in a pump gun. I've seen them, but have yet to be able to get my hands on one.

Accuracy at distance is a moot point for me as it's only use would be for finishing shots on coyotes when the dogs get to it before I do. I'll spare the details but suffice to say 12 gauge from 2 inches away isn't the best option. I carry a little cooey single shot in a scabbard on my back for such a purpose now but it would be nice to be able to just carry a little adapter in my pocket instead.
 
I actually want this for training with my kids.

I have a bunch of old 410 ammo kicking around (and no gun to use it in) my younger kids are apprehensive of shooting 12ga.

This would let them get the feel of the 12ga gun but only have the recoil of the 410.
With the goal of working up to the 12ga ammo when they are comfortable
 
These are made out of alluminum. No you cannot use larger calibers, period.

I remember a story from an old timer who said that a 30-30 round could be fired out of a 410. Go out grouse hunting and keep a 30-30 in your pocket. If the CO stops you, you are only bird hunting. See a deer, put a 30-30 round in and you are set? No not really.
A 30-30 with no chamber pressure and a bore larger than the bullet will get you a few hundred feet per second at 25 yards of you are lucky combined with the accuracty of a throwing axe.

Making things work on platforms they are not designed for only works in some mechanics, sometimes.

I have a kit that I bought from a now defunct company about 12 years ago that has 7 inch rifle barrels and as long as you clock the inserts the same every time (made a mark on mine so I can) all of the calibers I have shoot about 3 to 7" at 15 to 20 yards every time and I have been using them for the last decade.
Definitely by no means precision instruments but they are not meant to be and as far as a shtf scenario they definitely would be handy to get you to the bush taking care of nuisances along the way that would happen to have calibers you do not LOL.
But I digress, they really are more just fun for ####s and giggles

I had a 10" rifled 45 and 9mm.. Slapped it in a little DA backpacker. I just removed my ejector, and added couple more O rings. So when I opened the barrel. The insert stayed in.
 
I have a lathe and many years ago I made a .410 insert for my Stevens single 12 ga. Tolerances were not a major issue but it worked. Only issue was the insert wanting to eject and the price of ammo. I ran across it a year ago and thought about making one for .45acp. I had a piece of SPS steel that I was going to make a motorcycle axle out of years ago that never got used. This one I made with close tolerances and finished the bore at .450. The lathe that I used was an old Atlas that you had to change gears to change feed rate. With spacers and such I got affected rate of. 16" per revolution. I used the back gears as well. I made in a boring bar and silver soldered a tool bit to the end and the ground it on the lathe to a .454 diameter and about .040 wide. I did one pass through the bore and nothing broke so I quit. One groove is a bit deeper than the other and one a bit wider probably due to the difference in the cutter which I managed to drop and break one of the cutters.
I took it up moose hunting and we had a bit of fun shooting firewood logs and the odd spruce tree. Although the only sight was the shotgun front bead it was fairly accurate but of no practical use.
Just something to keep me busy in the shop

Its only more expensive if you're not sitting on a stockpile of .410 but all out of 12ga.

Or maybe you want to start your kid out with a gentler sort of introduction to shotgunning.

Thats exactly why I bought one - I have a single shot 12ga, but at 5lb it is NOT suitable for my kids. With a 410 adapter (which I do believe I bought from Frontier, thanks guys!) they can use it too.
