.22 extraction issue

I'm hoping all you clever minded people maybe able to help,
I have been given a old Remington model 12 pump action,the issue is it won't excract the LR cases they come half way out then jam and the excrator let's go,but excracts the shorts OK a bit tight but does extract them,
I've given the chamber a good clean and can't see any pitting or scoring in the chamber(well as best as I can see)
Any ideas or should I just retire it and keep it as a conversation piece.
Thanks in advance,,

Might need a new extractor.

It will extract a live round no worries,
Side note:I have only tried cci subs in it wasn't keen to try high velocity

Sometimes in those older 22 you could damage the chamber by dry firing the rifle. It would leave a small mark where the firing pin hits, over time it can cause shells to stick after firing. Unfired shells haven't expanded so don't tend to stick. An old mate of mine had this problem with an old BSA 15 shot B/A. Other than that as stated before a new extractor would be the answer I would be thinking.

Yep what Mooseman said. If it's a 12A it should be a take down model and once you get the bolt mechanism out you can inspect the front of the chamber. I used to have one and it fired supersonic fine. It didn't like blunt bullets tho' like the powerpoint ammo, needs pointy to ramp correctly.

the chamber might need a clean or tidy up
grab a little mirror and a torch and have a look see

Thanks muzza I'll strip it down tonight,i don't think it's the extractor because to get the case out I have to put a rod down the barrel and give it a good tap and I mean a good tap,

The chamber gets peened by repeated dry firing and the firing pin striking the chamber face,this forces metal to deform and a lip forms in the chamber. Most gunsmiths have a simple tool which is hardened steel and shaped like a chamber with a small area machined to allow insertion into the chamber around the deformation. A simple turn of the tool forces the metal back into position. I used to have one but lent it to a friend some 40 years ago. He ran off with my girlfriend and tool and has since passed away. I couldn't find it at the tidyup after the funeral .

Yep damage from dry fire is my bet
Get a gunsmith to tidy up the chamber
