(I never tried exactly that experiment with mine ... my dot had broken up into multiple dots ... I ran it through several ice storms and apparently that was bad ... so I turned mine in during the return program a few years ago)
I never had mine loose zero ... but I did have it conk out twice due to recoil (on a 5.5.6). I flipped up iron sights and continued.
Thanks. Lost my lease year before last and removed the batteries so I did not have to worry about leakage. Was going to shoot it as you suggested just seeing what everyone else had seen happen over time
