We shoot A LOT of deer here in Louisiana. In my lease we like a good blood trail and usually friends wait for friends to be a part of it in all but the shortest blood trails. It's part of the tradition of deer hunting. I don't kill a lot of deer (mostly by choice) but I have been on hundreds of tracking jobs with friends. You might say my friends are REAL MAD at deer.
Too many posts to read them all, but after hundreds of tracking jobs on wounded deer, my opinion on this is:
1) First and foremost, I always strive to get THE BEST SHOT ANGLE I can and will sometimes not take/get a shot waiting for that "best shot".
2) If the shot looks good I will USUALLY let him or her lay about 5-10 minutes. Dead is dead whether you go look at 10:00 or 10:10. There is no need to get down from the tree immediately, enjoy the experience.
3) On a shot I think is marginal, I will push the animal at least until I jump it twice. Continuing the pursuit depends on how fast the deer is moving after being jumped and how far they have gone before jumping it again. There is a lot to be said for pushing an animal that is marginally hit. IN MOST CASES, IF THERE IS BLOOD ON THE GROUND I'M GOING AFTER IT. The ONLY time I will stop pursuing a deer that's leaving blood is when we are approaching the limits of our lease (say within 250 yards).
4) Finally we will pursue EVERY deer within 5 minutes because of the predator population where we hunt. If you leave a deer overnight I can PROMISE you will not have it to eat the next morning.
I LOVE A GOOD BLOOD TRAIL!!!!!!!!!!
