I'm new to shotgunning. I live in a small town that allows hunting with shotguns ("single projectiles are not allowed"). I am in the process of acquiring written permission to hunt on several wooded properties. To access one of these areas (a nice oak ridge, hopefully with a good supply of grey squirrels and turkey), I need to walk through a wooded portion of land that is between two residential subdivisions. According to state law and municipal ordinance, I cannot fire a gun within 300' of a building. Now I certainly intend to be much farther away than that, I don't want to rub people the wrong way and get them all excited when my 20 gauge goes off; in fact, looking at Google Earth, I found a landmark that scales a good 500' from the nearest house that I intend to use as my 'stop and load' point. Now my question: If I'm loaded with high brass #6 birdshot, and I fire my gun with the barrel at a vertical angle of 45 degrees up into the air, how far can that birdshot travel? I have safe directions that I can shoot at treed squirrels; but if I'm really far back in the woods can I still shoot at a squirrel without sprinkling shot in someone's yard?
