I don't know if this is the best place to pose this question, but here goes.

Has anybody ever compared before/after accuracy with a common .22 rifle originally barreled and chambered in the short/long/long rifle configuration, and then relined with a dedicated .22 LR liner?

In theory I would think that a barrel set up for just the .22 LR would be more accurate than a compromise twist, but I wonder how that would actually play out.

I've done plenty of liners. They are accurate. You end up with a better fitting chamber than on an older rifle. The new crown helps a lot too.

All of that makes sense, as "restoring" is the basic reason .22 rifles get relined.

But, condition being equal, does the dedicated LR twist, etc., improve accuracy?

There has to be a reason that common sporting .22s used to have a barrel and chamber for S,L,LR, while the higher grades and target rifles were for LR only.

Perhaps my question can't be answered definitively, but I thought I'd ask.

I'd use an Anshutz for a basis. What ever twist is in those is the best for LR ammo.

1:16 seems to be standard for .22 LR barrels. I'd surmise that would be what Anschutz uses.

Of course there is more to accuracy than just the twist. I have a shooting buddy who has a short lined .22 with a Lilja liner about 16" long, with the rest of the barrel "freebored" with the rest of the 5/16" hole for the liner. He is a very serious target shooter, and he swears it is the most accurate rifle he has owned, bar none. Of course, he is sold on the concept.

I'm tempted to try it, but it would be an expensive boondoggle if it didn't produce a notable improvement in accuracy. I'd go with a common Redman liner. A Lilja isn't on my menu.

If your rifle is bad enough to require a barrel liner , then the liner would almost all ways show a improvement in accuracy .

True enough, but that wasn't the context of my question, which was more theoretical than the typical relining scenario to deal with a bad bore.

For example, NRA smallbore lever silhouette rules allow a relined original barrel, but not replacement. A shooter wanting to set up for optimal accuracy might try such a reline, even if the original S,L,LR barrel were in decent condition.

Thanks for all the replies.

If you shoot shorts get the twist for shorts (See Brownwlls).
I have had several rifles relined, the thing to watch is
if the end of the chamber is clean (no ridge). Other than
that they shoot fine. Avoid Numrich liners POS.

they always shoot better as the reason for relining is due to pitted bores. i did an old martini target rifle and it shot better than origonal. its bore was pretty good to start with. i have also done some 17 liners in bolt action 22 and they shoot great. one in paticular shot 1/2 in at 100 yds out of a ruger 77-22
