[QUOTE="Gone Ballistic, post: 492665, member: 26477"] In answer to your first question, I would say that your firing pin is off center which, by the way, is the case on many rifles. You didn't specifically state what type of action your firearm is. Most lever, semi-auto and pump actions are generally somewhat off center. If it's a bolt action it alsocould be somewhat off center. It shouldn't be a problem as long as your head space is within proper tolerances and your bolt face is square to the cartridge base. The second answer is that the case is held tightly against the bolt face when the round is fires, so the extractor has nothing to do with anything other than extracting the fired round. If your chamber was out-of-round it might cause case alignment problems with the neck but usually you would end up with a case splitting open. The same would happen if your headspace was too great.
