9mm also can be driven back in the casing. In fact, any round that doesn't get crimped in can do it. I have a couple 9s right now that are that way and need the bullets pulled and redone.
As to the original question, I rotate the ones in the mag if I unchamber a round. It might take a year to get back to the original round and by then, it should have already been shot at the range. So 2 or 3 at max.
Exactly. Since having had this "bullet set back" issue myself, I do the same thing. It was all part of the learning process.
