After removing bolt, taking it apart it to lube it, put it back together. Today at the range the extractor was not releasing the shell after firing, it was kind of stuck to the bolt. Had to remove the bolt entirely from the rifle in order to remove the shell. WTF was that about? I am guessing i did something wrong when i took it apart but that area of the bolt i never took apart, just the firing pin and stuff.

What to do?
