I just purchased a Savage Mark II 22LR rifle and am having problems with the extractor. The gun will not extract the spent shell when I cycle the bolt, and I have to use a knife to pry each spent shell out of the chamber. I've tried different brands of ammo (Federal, CCI, and some high dollar ammo, $4 per 50, of which I forgot the name).

The gun is very accurate - just need to fix above problem and tweak the trigger.

Any suggestions on how to fix this would be appreciated. Thanks.
