Shot this doe at 25yds . Watched the shot and it was perfect. Got down 40 minutes later . Proceeded to track for over 680 yards . Never had more than quarter size patches of blood with bubbles in it , mostly pin drops to follow . I jumped her after about 300yds . Jumped her again a couple hundred yards later and she stood up slowly and tipped over . One blade was broke off the broadhead and the expansion cup was cracked wedged prevented another blade from opening . This deer must have iron lungs . When I field dressed her , both lungs had a hole in them . The exit was just as big as the entry hole.
