SOS!!!Older savage model 12 bolt help

[1coolcat]

Hey guys I just picked up an older savage model 12 in 17 fire ball. It's a left hand bolt rifle and I wanted to disassemble the bolt. I've watched some you tube videos ..my bolt has a spot for a hex wrench and it will not budge..I don't want to break anything..but I want to inspect the firing pin as it just sounds slow when I dry fire.. perhaps it need a new spring, or a good cleaning ..I know on left hand Remington bolt actions the bolt is reversed thread..I'm not sure about the savage model 12..
I could really use some help here..any idea's
