If you are shooting from the ground, and the ground is flat, any bullet shot at a deer will go further than one shot at the same deer from a treestand.
I'd guess most misses (shooting on flat ground) will hit the ground within 150 yds beyond the deer. On frozen ground the bullet may bounce along for some distance and this can usually be seen if there is a little snow cover, like an inch or two.
IMO, there's no way a miss on flat ground should go a mile. But, you never know with ricochets. If the bullet is deflected at an upwards angle it could certainly go a considerable distance.
