Indiana opened up firearms deer season this year to allow select rifle cartridges. I am thinking about using a .243 but want to be sure it is safe. Indiana is pretty flat and I usually hunt field edges with woods nearby. How far is needed to feel comfortable taking a shot when there are houses in the distance if hunting from an elevated stand? Obviously not going to shoot directly towards a noise that is close but what about a house 600 yards away? .5 miles away? 1 mile away? When do you have to worry? Especially if there are woods in between ?
