Then unless it is a combination of two seperate problems (one being a foreign body or burr in the workings of the bolt/reciever), then it looks like an issue in the chamber, probably a build up of carbon or other shooting muck.

Have you tried chambering then ejecting a live round and comparing it to a fresh one to observe if there is compression of the projectile or scraping of the cartridge?

Another option is to just try chambering some other types of .22 and see if they fit. Some target .22 rifles struggle to chamber or extract some types of .22 ammo.
