I have a Savage model 6 semi auto and it has not worked for quite a while, can't pull the trigger and bolt won't slide back. Problem started years ago when it would fail to eject or feed a new round, had a gunsmith repair it but after a few hundred rounds problem started over again, as I mentioned it won't do anything now. Is there a possibility that I can purchase a complete new bolt and associated parts, if so where might I be able to find such parts. I would really like to start shooting this old gun again.
