I am having a problem with a Ross Cadet .22 cal rifle that I recently acquired. Spent casings are very difficult to extract from the chamber. I have quite aggressively cleaned the bore and chamber with a brass brush and Hoppe’s 9 bore cleaner but have not seen much if any improvement. The bore has some pitting, evidence of past neglect but the gun is an accurate shooter. I was wondering if anyone has encountered and fixed this kind of issue before?
Difficult casing extraction on .22 cal rifle

I did this once for a rifle/ammo combo and it worked well. I took a couple boxes odf 22 ammo and dumped them in a Tupperware container and squirted them with a little silcon lube, then shook.
The lube seemed to solve the problem. Try a couple rounds before doing a few boxes.

Probably been dry fired many times and the mouth of the chamber has a burr. You can buy a tool to force it back out or just do a DIY fix to get rid of the burr.
Turkinator replyed, "just do a DIY fix to get rid of the burr."
indulge me for a moment and expand on the DIY burr fix. What does this involve?
There is no crud under the extractor, condition of the chamber is difficult to see. I would assume there is some degree of chamber pitting based on what I can see of the overall bore condition.

The firing pin on the Ross was probably made out of a lot harder metal than the barrel was meaning every time the rifle was dry fired it would have peened the opening of the chamber a little bit. Reeming the area the firing pin contacts the chamber face may fix the problem. If you feel a lip there it would be best to either take it to a gunsmith or buy the tool and force it back out yourself.
A friend's 1980's vintage Walther GSP had problem's extracting cases.
Airgunsplus suggested a brass .22 brush in a drill to polish out the carbon and lead in the chamber.
Takes some time to do it carefully without getting into the throat too much, but it's fired about 200 rounds since with no problems since getting this treatment AND shot it's best group to date.
BTW: also used some Wipeout overnight between drilling.
Chamber is not mirror smooth now. Can still see some front to back lines, but much smoother than before the brush and drill.

That is an interesting statement. Many different brands of 22 ammo use lubed cases. So far (over 100 years) has not seemed to be a problem.
I shared what I had done (lubed the ammo) and that it worked. Those are two facts. The gun was a blow back Norc 22 pistol.
Agree. all the 22 ammo I use is lubed, no copper washed for my guns.
As for center fire: http://carteach0.########.ca/2009/01/75x55-swiss-gp-11-weighed-in-balance.html
In Bullseye pistol shooting circles it is very common to put a drop of oil on top cartridge in the mag to ensure extraction of 22lr ammo after the first alibi.

There's your answer- it's perfectly safe, since Sunray lives in Superman's Bizarro world, where everything is opposite. Look at most of Sunray's 22,000 + posts and draw your own conclusion.
If the rifle has been fed a diet of .22 short in the past, there might be some erosion in the chamber area just ahead of the case mouth. When you shoot .22 long or long rifle in the same rifle, the longer case bell mouths out into the eroded portion making extraction stiff as the pull has to overcome the flared out brass and neck it back down as it extracts.
Examin the mouth of your cases to see it there is a shiney ring where the metal has been abraided on the outside edge. If you can find some .22 shorts to try, that would be a good litmus test.
I agree that lubing cases in some high power center fire guns is not good a good idea as lubing does not allow the case to grip the chamber walls on expansion. Extra thrust is put back onto the bolt. Not a problem with .22 rimfire as the action is usually well strong enough that it doesnt make much difference. With a blowback system, extra thrust is good and helps it cycle.
Often proof rounds are lubed to capitalise on this extra thrust to set bolt lugs down into their corresponding pockets.

Do you even read the OP? He stated there is pitting. And 22 LR isn't going to generate enough chamber pressure that lubing will make any difference at all. You can hold the bolt closed with your thumb for pete's sake.
spelling and grammar count...so should reading comprehension and common sense
Yesterday I had a chance to further test the gun with different types of .22 ammunition. The difficult/stiff extraction occurs with all the .22LR ammunition I have tried, but .22 short cycles with ease. I think Englishman.ca has hit the right diagnosis, a past diet of .22 short ammunition and some related chamber erosion. Is there a fix for this problem, something that I could do at home with limited tools?
Other than fitting a barrel liner, I don't think that much can be done if anything about the erosion. Once the metal is gone. it's gone.
Live with the hard extraction or feed it 22 shorts would be my answer.
