How is shot pattern used to make a distance determination for shotgun blasts? What factors other than distance to target can affect the distance determination?
What will be an ideal response?
Distance determination for a shotgun blast is made by measuring the spread of the discharged shot—the wider the spread, the farther the shooter was from the target. Other factors include the barrel length, the size and quantity of the pellets fired, the quantity of powder charge used to propel the pellets, and the choke of the gun (the degree of constriction placed at the muzzle end of the barrel).
