I have a .22 Crickett rifle for my daughter and just started having a problem with it. It has about 1200 rounds through it and is a year old. Yesterday I took her shooting and when you would pull the bolt back the extractor would let go of the rim. It didn't matter if you pulled the bolt slow or fast. So last night I clean it up make sure that the chamber is clean and smooth and clean the extractor the extractor push rod and the spring. Today same crap. the extractor lets go of the rim. I did notice last night that it looks like there is a groove forming on the barrel just above the chamber from the 12:00 to 3:00 position, looks like part of the extractor is making contact and causing this quarter ring around the chamber. anyone got any ideas, gonna call the manufaturer tomarrow.
