As to the deer hunting on small properties, where I am at, that is the norm more than the exception. One good way to deal with that is a lot of the hunting is done by tree stand so that the angle of the shot will put the bullet into the ground within the general vicinity of the animal, even in the case of a miss.
Thank you 
Deer, hog, or any animal hunting is kind of a different beast than target shooting.
The biggest factor is after an animal hit the thing in some cases, still walks/runs away while bleeding out. On 2 acres it could easily cross a property line. Then you’ve got to cross maybe multiple properties and in the end maybe dispatch the dieing animal in a neighbors yard.
Where I’m at, even though we have a ton of land I have approach both my neighbors and told them, "if they ever shoot an animal on THEIR land and need to cross onto my property to track a blood trail and retrieve it, that this is ok. They of course reciprocated.
My experience growing up was more that we’d hear “bang bang bang!” and realize it was opening day. Then we’d go grab our green and orange vests to make sure the hunters could see us if they strayed into our neck of the woods.
