I have about the same amount of shot thru mine also.I think mine is finally done stretching but i still take a couple shots before hunting just to make sure i'm still on target.

If it's the Zebra....good luck. If it's the Tiger you should be there now. Don't just resight, you need to recheck your draw length, draw weight, and cam rollover, they all change with string stretch.
