Hello all, I know how hard it is to get 22 liners in Canada...so my question, can you uses a 22 pellet gun barrel as a liner. The ones I looked at were 1 to 17.74 inch or 1 to 450mm twist rate...but they are here, in Canada...so what do you think?...might be good for short barrel, the ones I found are fairly small in o.d. Barrels are brand new, never be used....So just asking...I’ve never done it(used a pellet gun barrel ) on a 22 rifle.
Cheers

I wouldn't... weaker for sure... and it the bore groove diameter correct ?

I don’t know...don’t have one here in my hands...that why I’m asking...it would be used, as a liner...so minimal thinkness, or boring required....just a little out of the middle lol. You never know..if you don’t ask, and I rather see if someone has done it before...was looking at the 17 cal too, was thinking old NFG Antique status revolvers. I’ve had a couple in the past that had very bad bores, ended up being parts guns.
 
Standard Ruger 10-22 take offs seem to be readily available & reasonably inexpensive .
I have used them for donor bbls on a couple projects eg. Stevens Favorite .
They can be turned down for a liner
 
I don't have a follow rest for my lathe. The thought of turning down a rifle barrel to 5/16" - size of my liner drill - makes me nervous.
 
When I wanted a barrel liner I just ordered one at Reliable Guns in Vancouver. Within a few weeks I got a call saying the Redman barrel liner was in, so I walked a few blocks and picked it up. The 'being in Canada' tax was fairly steep but hey, that's the cost of being Canadian I guess. This is the Brownell's page for the .22lr liners:

As I understand it airgun barrels are a bit softer steel, but I could be mistaken. Rifling shape and depth varies quite a lot between airgun barrels too, there is no standard really. But a .22lr bullet pulled from a case will push through .22" airgun barrel, generally speaking, with a brass rod and some light tapping. At least it did when I tried with an Industry Brand .22" barrel from a QB78D.
 
Yep I hear ya on the alternatives to buying a liner, was also thinking of turning down a barrel,but these barrels ,( think one was a walther’s match barrel ) were all under $100.00 Canadian... so price was at par with Brownell’s,or lower, after shipping for US..to Canada...etc. And there already here in Canada!
And yes I do have a couple Stevens...one favorite, and a Marksman , one with a Newer Stevens barrel ( can’t remember the model) but newer bolt action barrel, and another with a Cooey barrel, both work great.
But was looking for a bore and replacement type ,liner system , so I could leave the old writing...sights etc..where they are....mostly think of older antique types...so low pressure...small caliber...etc. Revolvers...
Thanks for all the replies.

if a liner is installed properly, it is supported by the main body of the original barrel. The real issue is the twist rate and the bore dimensions of the air rifle. My guess is the twist rate will be too slow for a 22 rimfire

A minor point of note, an air rifle barrel for 17 caliber will not work as the firearms bore diameter is .172", not the .177" of the air gun bore.

All that aside from materials used, and twist rates.

A unfired .17 bullet will drop freely through an air gun barrel. Accuracy would be...problematic.
 
OP, go to your local gunshop and ask if they have a barreled action or parts rifle with a decent 22 RF bore. Cheaper than a liner and they may even have one for the same model rifle you already have.

Now the only is whether or not your barrel is press fit into the receiver and pinned or not.

Even then, you could take the parts from your rifle and use them to complete the newly acquired barreled action.

Likely a lot cheaper in the long run.

22 pellet rifle bores are usually .218 diameter, about .005-.007 less than modern 22 LR barrels.

Some of the older 22 RF barrels had an actual bore diameter of .220. I have a Martini with such a bore and it shoots modern ammo very well, without any ill effects I can see.

As mentioned, the pellet rifle barrels are a bit softer. Enough to make a difference at such low pressures??? Not likely. I agree the throats would burn out faster. Most people don't shoot enough to do it though.
