So i have been looking into this and have watched the videos that were posted before on action work and was wondering do you always change the bolt to a tighter fitting (over sized) bolt when this service is done to the action? If it is not required, when is it recommended to do so? I ask because i am contemplating getting a new bolt knob installed on my factory rem700 bolt but don't want to waste the money if i just am going to replace it when i do the action work?
