I've shot thousands of high velocity .22 LR bullets at paper targets from 25, 50, 75, 100, 125 and 150 yards and several points in between {my back yard range has target frames set at 35, 45 and 65 yards presently}. I've never seen any indication of tumbling or instability and like I said before, if you were going to ,you'd see it within the first 60 yards or so and it would show in the form of oblong or out of round holes on paper.
