Yes, I agree with others, you did everything right. To me, I feel that more deer are lost because the hunter pushed the deer too soon and too often. If it's a fatal shot, you'll find him close by, if he's hit hard, let him go and begin tracking him down after 30-60 min. Either way, let him go. I also feel it's OK to go to the exact spot the deer was standing when you fired. That may give you a good indication of how hard the deer was hit. You can also tell by where the deer was hit when shot as well as how the deer reacted when he ran.

Also, I woud continue to hunt that same property. He's not the only buck in those woods.
Again, congrats on a nice deer.
