I am rather excited to have found a location to make a 1300 and change yard shot in western central Virginia using 308s and 7mm 08s. My question pertains to how much space behind the target is required to be considered "Safe". Behind the planned target zone, through a grove of trees, and on the back side of a hill there is a house, which I ranged via google earth at 1900 yards. The house is not in line of sight from the impact area, but is partially visible from the shooting position. Is that enough of a margin to be considered safe, or should I waive off for fear of an errant or ricocheting round hitting the house? Thanks for your thoughts.
