While in college I was part of a team that had a collection permit for research. We killed deer from the end of season (first of January) in a high rack with spotlights till bucks dropped their antlers and we couldn't tell bucks from does easily. In 3 years we killed over 1000 deer. After that I got to harvest waterfowl with a supressed .22 off of the water and testing them for bird flu.
After that I really cut back on hunting as I just didn't want to shoot anything else for a long time.
That's not really "hunting", but stone cold killing. There is a difference.
