I dialed the scope to 5X and put the crosshairs on targets at 300, 400 and 550 yards and then moved my head side to side and up and down to see how far I could get the crosshairs to move on the target with no parallax correction. At 5X, I could get the crosshairs to move 3 inches at 300 yards, 6 inches at 400 yards and 10 inches at 550 yards.
