Tikka T1x will not eject a fired case frame the chamber. Approximately 500 rounds fired from the gun. It was fine for a while, but started leaving fired cases jammed in the chamber. It will extract non fired rounds, in chamber. Bolt has been cleaned, chamber cleaned. The extractor won’t go over the case rim of a fired case. There’s a “fix” to remove a small amount of material from the extractor, but that hasn’t changed anything.
