[QUOTE="ofbandg, post: 2627081, member: 91402"] When you chamber a round the bullet isn't all the way home until the bolt handle is dropped because the bolt lugs are tapered. Normally the bullet isn't seated out so far that it will engage the rifling before the handle is dropped so it's free to turn with the bolt until it engages the rifling which should only happen in the last part of the rotation - and the first action of the engagement would result in the case being fully pushed back against the face of the bolt. If the bullet is seated out so far as to engage the rifling well before the bolt handle is completely down, whether the bullet turns in the case, against the rifling, or against the bolt face, would depend on the amount of friction in the various contacts. That is how I understand the process. If I am missing something please let me know. [/QUOTE]
