mauser 06.. I always clean the threads with a very small brush you can buy for cleaning the breech plug hole on the modern inlines. It works perfect for cleaning the threads on the vent liner. I wrap a thin patch around it and slowly turn it into the threads. It really leaves them clean. Q-tips will also clean in there.
I am so glad you got it out. Sometimes when things are going bad for me I just have to put the thing down and come back to it at a later time after I have calmed down.. I've even been known to do serious damage to things when frustrated.
Next time it will work better....
