Sub-calibre inserts

Does anyone know where a person could get rifled sub-calibre inserts in Canada? I'm looking specifically for a .22LR insert for a 20 gauge. Anyone have experience with them? Do they work well? How's the accuracy?

Thanks!

I wouldn't expect much accuracy or performance wise from what is essentially a 3" offset barrel.

^My recent experiments with one of these rimfire adapters for a shotgun, demonstrated very unreliable ignition.

Out of six, four were misfires. It's set up like the one in mmat's post, the firing pin directly to rim.

yah!

Edit: At least with a centrefire pistol calibre variant, reliability is one positive trait. Accuracy is another issue altogether.
Just my own singular personal experience btw.

Many of the reviews I've seen indicate that they aren't very accurate, but I haven't seen any that complain about their reliability. Makes sense though if the chamber offset isn't just right. I ordered one from GaugeMate in California just to mess around with. I'll try to remember to post up a review on here once it arrives. I don't have high hopes though. If by some miracle, it does prove to be reliable and "accurate" (I'm talking inside 25 feet) it could be a good way to pick off a grouse or rabbit on the trail without blowing it to smithereens.

I had a few gaugemates, never 22LR tho. Only the 7-10" model adapters. I noticed shooting my 45 adapter that the firing pin from the 12GA would almost mushroom the WHOLE primer. Prolly why they're not that great in 22LR. since most 22 firing pins are square and flat.

That's fair enough. Myself I have a few of these, and the only ones I would consider doing exactly as you say here, is with the adapters that will chamber 38 Special.

Cheers!

I received some updated Shortlane 12G adapters from Pathfinder recently. They have the finger groove for extraction and O-rings unlike the original design.
Had it out at the range the other day with my short single shot that I bought from Corwin a while back and I was impressed with the results.
Hitting golf balls was fairly consistent out to 25 yards with the misses just missing. I was using bulk federal and the shotgun has a basic bead sight.
Winter project will be adding better sights to this gun so I can dial it in for even more precision.
The kit I got was about $100 and came in a leather pouch with 3 adapters, .22lr, 9mm and a .410/.45LC.
 
I was going to order from them but they won't ship to Canada. I almost asked my buddy to order them for me (he has a US postal address) but then I saw GaugeMate was happy to ship to Canada so I went with them. I hope they turn out to be as good as the Shortlanes are.

Did you get the 16" Warrior from Corwin? I just ordered the 20 gauge version of it. I can't wait for it to get here. Care to post any pics of yours?
 
They used to ship but don't anymore.
For some reason Pathfinder will still ship their "pathfinder" models of the short lane adapters.
Not sure why or how but they are shipping north...and they work well from my experience.
I wasn't able to pick you the 9mm cases with my fingernail but the .22lr were a breeze to remove.
The shotgun is one of the first one's that Corwin brough in with the 13" barrel, 12 gauge and allum receiver so quite light weight with the plastic stock.

Here's a cold link for a source.

The only negative with the short lane's are that they rust, so oil or wax them up for protection.
Mine arrived recently with rust already setting in.
A guncoat paint job of some sort seems would be a good improvement.
 
My guagemate was excellent. I'm just waiting for a short barrel single shot that's better then a DA. I was shooting my 10" 45 ACP rifled adapter from a 13" DA, to 200Ys.
 
Neat gizmo. I've got a Hammond game getter for my .308 which fires 1 pellet of 00Buck with a nail gun blank.

I deer hunt with my 12ga pump a lot though, and a similar quiet grouse getter would be nice to have.

I'm no machinist, but it looks like it would be pretty easy to whip up a smooth bore version of that on the lathe pretty quick. I wonder how accurate a smooth bore .22 version would be at 5-10 yards? Or 9mm?

If it tumbled right away, I wonder if it would risk hitting the barrel?
 
IIRC, they make a smoothbore version so you're probably good to go on making your own. I wonder if you could over size the hole and simply press fit a short section of an old .22 barrel if you wanted the rifling.

There is someone who posted on youtube a slow motion video of himself firing the shell sized shortlane out of his 590 shotgun.

The tumbling is pretty obvious in his excellent video presentation.

Couldn't find the video, but I trust your description. I saw some other vids, and you could clearly see the key hole entries on the paper at 30 feet, yet it still grouped 4ish inches.

An excellent idea! I completely forgot about that 9inch chunk of .22 barrel sitting on my work bench from an old project.

But on second thought, because .22s are rim fire, the hole would have to be offset. That thick Cooey barrel it probably too big to off set properly :-/

Yep, I think these are still viable for the intended use, if the user is fully aware of the limitations here:

-close range use
-terminal power limits
-expect realistic accuracy, especially in a shot shell size adapter, so don't expect it to shoot like a Cooey rifle

I still think these can still be very handy in dense tree growth within normal hunting distances of the smaller forest dwelling critters.

I think you'd have to first fabricate the insert and then drill an offset hole. Then you'd have to turn down the .22 barrel and press fit it into the offset hole that you drilled and maybe even solder it in place to make sure it doesn't move.
