You wrote"he bucked and ran off" if he bucked like you said and that was just not a expression...he's hit pretty well. Are you sure you did not get off his track when you started? Go back, relax and start over slowly. Place your hat at the point of impact thats first...so you can judge distances if you can still see the hat. Do you have ANY hair at impact? if so what color is it? Think to yourself how far did you see that buck run off before you lost sight...make a mental note of compass direction. Was he hit on the right or left side...he will favor his hit side everytime, they look for water when hit if they can get to it within reason. BRING a buddy with you (no weapon for him), more eyes looking will help... but stay as a pair and work slow...you are the one with the weapon so you are in front at all times...he's looking down for blood you are looking for the deer...YOU CAN NOT GO SLOW ENOUGH. Good Luck
