For the first time ever I had some light primer hits yesterday with my model 600 . Same cci primers I always use well formed neck sized only brass primers seated how I always do . So that leaves me with the pin/ spring either starting to get weak or just gummed up , which is a possiblilty last season I hunted in the rain for two days and it got pretty wet so I hosed the bolt down with WD40 . My question is can I take the bolt apart without the need of a special tool? I have never had it apart since 1964 when it came from the factory . I want to at least rule this out since there's only 2 weeks left till deer season starts .
