I feel the pain expressed here. This has happened to many deer hunters who have been at it awhile. I am 60 years old and have had this experience twice out of many deer shot and recovered. One was an average 9 pointer I found about week later. The other was a huge bodied wide-racked 10 point that I found 2 days later by raven squawking within a half mile of the main search area.
Both of these losses were while still hunting on our hunting grounds less than 20 miles from the Canadian border. I sawed off the racks, but it is just not the same as recovering the animal while still being able to use the meat. It is hard, but has to be accepted and learned from..but they are extremely tough animals and it is a reality of deer hunting.
Within our hunting party this has happened to our son, my cousin, and my brother-in-law. My hunting buddy going back to high school days came within a whisker of this happening to him after breaking a front leg up high on a big boy, but he was able to keep after him among other deer tracks due to the drag marks in the snow from his broken leg.
He shot him at about 8 am and it ended up being an all day affair through some of the nastiest brush in the country with all kinds of twist and turns, circling, doubling back, jumping him a few times, then finally finishing him with a neck shot several miles from where it initially shot. We got back to the kill sight after dinner, quartered him up by headlights, and back to camp near midnight.
